WIKA, Model A-10 Pressure transmitter

Pressure gauge and thermometer are suitable for the various pressure and temperature measurement applications. We offer solutions for gas and liquid measurements. The range covers capsule, plate or Bourdon-tube pressure gauges and measuring instruments made from various materials with versions extending from standard models to stainless steel versions, for use in corrosive environments, and electronics measuring equipment.

The pressure transmitters of the 21Y series have no internal seal and a high insulation voltage of 300 VDC, and are extremely resistant to environmental influences. The sophisticated compensation circuit makes it possible to specify a narrow total error band. A wide range of pressure connections and electrical connections are available to choose from.

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.

The industrial pressure transmitter DMP 334 has been especially designed for use in hydraulic systems up to 2200 bar. The base element of DMP 334 is a thinfilm sensor, that is welded with the pressure port and meets high demands of foolproofness and reliability. All of characteristics and the excellent mesurement data of DMP 334 as well as distinguished offset stability offer a pressure transmiter with easy handling, reliability and robustness for hydraulic user. The DMP 334 is deliverable with pressure ports of extrem pressure technics. Features: — nominal pressure: 0 ... 600 bar up to 0 ... 2.200 bar — accuracy: 0.35 % FSO — pressure sensor welded — extremly robust and excellent longterm stability Optional Features: — IS-Version Ex ia = intrinsically safe for gases and dusts — pressure port M20 x 1.5 oder 9/16 UNF — adjustability of span and offset — different kinds of electrical connections
