In practice the requirement often arises to convert the measurement signals of a sensor into a standard signal in the simplest possible manner in the immediate proximity of the sensor. This permits trouble-free, low-loss transmission of measured values over longer distances to an instrument board or plant controls. Ideally suited for this purpose is the in-line measuring amplifier, which is inserted in between in the connection cable by means of plug contacts. Owing to its compact, robust design and low weight, it finds use in almost any application. Even movable locations subject to forces of acceleration, for example manipulators, present no problems. It is intended mainly for use of control cabinets in just about any location and is matched to a specific sensor. The aluminium housing is extremely sturdy and affords the greatest possible protection even in harsh environments.

The new 9250/9251 amplifier generation unites all the features that make modern measurement data acquisition actually possible for the first time. Network-compatible, high-precision, user-friendly, smart and versatile: the combined system of amplifier module and bus controller can be integrated into any existing setup. The amplifier 9250 in conjuction with the fieldbus controller 9251 takes signals exactly to the point where they can be combined, monitored and linked efficiently to other data. The fieldbus interfaces give you flexibility, speed and perfect connections, and save you time, money and other resources when integrating your measurement setup with existing systems. Automatic sensor recognition due to burster TEDS lets you play absolutely safe, protecting you from setting incorrect parameters. The broad supply voltage range permits operation on standard power supplies used in switch gear cabinets.

Situations often occur in practice in which it is necessary to place a measuring amplifier immediately in the neighborhood of the sensor in order to be able to access a standard signal there. In this way, long distances to the evaluating electronics can be covered. This task can ideally be performed by the 9236 in-line measuring amplifier. With its high degree of protection (IP67) its singlechannel version can be integrated into the application even in the tough environment outside the switch gear cabinet. — Automatic production machinery — Laboratory measurements — Integration into customer‘s circuit boards — Field measurements Features: — Operates with up to 4 measuring channels — Voltage output 0 to ± 5 V / 0 to ±10 V — Protected against reverse connection and short-circuit — Also available as circuit board without housing — Simple configuration using DIP switch — High degree of protection up to IP67

The amplifier module model 9243 is used wherever measurement signals from strain gauges, potentiometric sensors or DC/DC sensors have to be converted into standard signals. Simply by mounting on conventional DIN-mount rails, it is possible to position the amplifier module on location, in the proximity of the sensor. Especially for rough environments a IP65 version is available. The broad auxiliary power range and the choice between AC or DC permits operation on standard power supplies used in switch gear cabinets. A highly precise reference voltage source is built-in for calibration purposes. A calibrating shunt can also be connected via two separate terminals. This permits deliberate detuning of a strain gauge sensor for calibration or merely to check the measuring chain.

The new strain gage amplifier with IO-Link interface enables digitalization of the measurement technology right from the sensor. Its compact design and high degree of protection allow the instrumentation amplifier to be used practically anywhere in the field. Strain gage sensors typically have an output voltage of a few millivolts. In industrial environments, e.g. in the vicinity of electric motors or frequency converters, interference can affect the measurement result when transmitting analog signals. This is reliably avoided using the new strain gage amplifier with IO-Link interface. The analog link between the sensor and instrumentation amplifier is kept as short as possible, the standardized IO-Link communication is fully digital and interference-free. The amplifier is powered directly via the IO-Link interface – a standardized 5-wire cable with M12 socket. Strain gage sensors can be connected via a 4-pin M8 connector.

The newly developed sensor PROFIBUS module model 9221 is predestined for the integration of various analog sensor output signals into complex, net worked and peripheral automation structures. This module finds its fields of application in the industrial automation technology as well as the test rig technology based on its secure and reliable transfer mode, the fast transfer speed and its simple construction. The inputs (e.g. PLC signal gauge) and outputs in addition to the external control allow a zero compensation by trigger via proximity switch or fast alerting on passing of set point values. Industrial type connection and mounting techniques enable the user the adaption and integration in the existing mechanical and electrical environment. The excellent quality of measurement together with the high grade capture of mean values also enable the application in research and development. The use of standardized PROFIBUS protocols makes the connection an easy task for the programmer.

Network-compatible, high-precision, user-friendly, smart and versatile: the combined system of amplifier module and Fieldbus controller can be integrated into any existing setup. The Fieldbus controller delivers all signals exactly where they are needed, to be combined, checked and linked. With the available Fieldbus interfaces, you are flexible, perfectly connected and you save time, costs and other resources when linking to and integrating into existing systems. Due to the integrated measuring input, the use of a Fieldbus controller module is sufficient for single-channel applications. For multi-channel applications, the system can be expanded to up to 9 measuring channels. Up to 8 bus-compatible model 9250 instrumentation amplifiers can be cascaded on the model 9251 Fieldbus controller.

Inductive displacement sensors of this series measure linear displacements and indirectly all mechanical values convertible into displacements by additional equipment (i.e. tension and compression forces, extension, torque, vibration). The sensor body equipped with a connector has an outer diameter of only 8 mm and therefore is especially well suitable for the integration in dimensionally restricted structures. Typical application fields are displacement and extension measurements on: —Machines —Servo systems —Motor vehicles —Test benches —Production plants The cylindrical case made of stainless steel, houses a differential transformer (LVDT). It consists of a primary and two secondary coils with axially moveable core. A displacement of this core changes the magnetic induction of the coils. The INLINE carrier frequency amplifier converts the displacement into a direct proportional electrical DC voltage.

The pressure transmitter illustrated here measures differences in pressure between the two connections of the measuring element. Pressure differences can be measured with respect to a reference pressure, such as atmosphere, or to the command variable of a regulation system. Equally, however, it is possible to measure pressure differences within systems that have a high static pressure. One practical example of this would be measuring a flow rate by determining the pressure drop occurring across a metering diaphragm. The differential pressure transmitter measures in both directions and can therefore, for instance, be used on double-acting hydraulic cylinders. Its construction permits it to be used with liquid or gaseous media. Venting holes simplify installation. The robust design and the use of stainless steel make it possible to use the pressure transmitter under tough operating conditions.

EGE compact devices for the flow monitoring of gaseous media contain measuring and amplifier in a single housing. They are used where a visualisation of the flow rate on site is required. EGE flow sensors for gaseous media feature two pins which contain the thermal measuring elements. The sensors are set up directly at the device. EGE sensors for gaseous media are characterised by a rapid response capability and reliable operation. Based on the principle, there are no moving parts in the air flow monitors and they can, therefore, also be used in aggressive environments. Devices for air conditioning technology have smooth measuring surfaces and need not protrude far into the flow duct.

EGE flow sensors for gaseous mediums without integrated amplifier permit the space-saving flow measurement on site and the comfortable setting of the limit value using separate amplifier, e.g. within a control cabinet.
