SENSOCON INC. - Differential Pressure Gauges & Switches

Differential pressure transmitters are used in a large variety of applications and systems to monitor positive, negative or differential pressure and send a corresponding electrical signal to another device such as a panel meter, PLC, or other data acquisition device. Sensocon has differential pressure transmitters for measuring air and gas as well as liquids with our wet/wet differential pressure transmitter. All of our differential pressure transmitters come standard with a 4-20 mA output, but we also offer an optional 0-10 V output. Our differential pressure transmitters come with different accuracies from 1% to 0.25% and some come standard with a certificate of calibration while an NIST traceable certificate of calibration is available for all products. Our product family includes a low-cost, weatherproof differential pressure transmitters as well as a wet/wet differential pressure transmitter with all stainless steel wetted parts and construction.

The Series DPT Multi-Range Differential Pressure Transmitter was designed specifically for the building automation and HVAC industry. With field selectable ranges down to 0.1 inches w.c., this product is ideal for monitoring building pressure, static pressure, differential pressure, or air velocity and flow. The Series DPT Differential Pressure Transmitter also has jumper selectable outputs for 4-20 mA or 0-10 V and unit selection giving additional flexibility. For a virtually maintenance free transmitter, order the optional automatic zero and the transmitter will perform its own zero point maintenance. The Multi-Range Differential Pressure Transmitter also has an optional backlit LCD for giving local indication.

The Series 211 Differential Pressure Transmitter can accurately measure positive, negative, or differential pressure and send the corresponding 4-20 mA output signal. The Series 211 Differential Pressure Transmitter is not position sensitive and can be mounted in any orientation without compromising accuracy. It also features a power LED, so you always know when the transmitter is operating. The compact, lightweight design makes installation simple and easy.

The Series 212 Weatherproof Differential Pressure Transmitter can accurately measure positive, negative, or differential pressure and send a corresponding 4-20 mA or 0-10 V output signal. The Series 212 Weatherproof Differential Pressure Transmitter is designed with an IP 65 enclosure and can be easily mounted to any flat surface. The Series 212 is not position sensitive and can be mounted in any orientation without compromising accuracy. The compact, lightweight design makes installation simple and easy.

The Series 251 wet/wet differential pressure transmitter utilizes a double diaphragm sensor technology that outperforms standard double sensor products in accuracy, reliability and static operating pressure. This differential pressure sensing technology offers 0.25% accuracy with static operating pressures up to 1000 PSI. The Series 251 features 316 stainless steel construction designed to meet NEMA 4X (IP 65) standards. The transmitter also offers exceptional field flexibility with a 5:1 turn down and comes standard with a certificate of calibration.

The Series AFA Siren™ Air Flow Alarm is an airflow monitor designed to provide visual and audible indications for decreases in airflow. Its color changing LED's provide vibrant visual indication of the operating status of the unit. A crisp and clear audible alarm will sound when airflow decreases below the designated set point. The Siren™ offers multiple mounting options including bracket mounting and interlocking strips. The unit can be powered through the 6-position terminal connection or by use of a power adapter. The Siren™ offers the ability to customize the minimum velocity set point should there be a need for a set point greater than the standard 80% of operational velocity. All units come standard with a night set back option for those who are energy conscious. The Siren also fulfills the exhaust alarm requirement needed to be in compliance with NSF/ANSI Standard 49. A quick installation process, one-touch calibration, and one-touch reset make for an easy set up and easy use.

The Series JFM-P FloSen® Airflow Meassuring Probes provide accurate, repeatable measurement of air movement in HVAC ducts. Its patented elliptically-shaped sensor design with improved aerodynamic characteristics outperforms more traditional devices, and overcomes loss of accuracy caused by fluid separation at the sensor body. It is designed to maintain a constant parallel airflow pattern over the static sensing ports for more accurate, steady signals under all duct conditions. The elimination of separation results in a stabilized static pressure signal, helping to eliminate “hunting” during fan control. FloSen® Airflow Probes utilize a unique in-line groove for total pressure sensing and dual ports for static pressure sensing which produces a higher differential pressure for very low velocity measurements. The total and static pressure measuring points are distributed for equal-area averaging of flows resulting in improved accuracy and reliability.

The Series AFS Air Flow Sensor is a differential pressure air velocity sensor designed to measure average air velocities in VAV terminal units and HVAC ductwork. It has an aero-dynamic elliptical shape resulting in a minimum pressure drop and amplified differential pressure signals which allow accurate measurement of air velocities from 300 fpm to 5000 fpm (1.5 m/s to 20 m/s). It includes multiple sensing points aligned in line grooves to measure total and static pressure. It is easy to install and cost effective. Series AFS Airflow Sensors are perfect for VAV Retrofits. The AFS is a differential pressure air velocity sensor designed to measure average air velocities in VAV terminal units and HVAC ductwork.

The Series VTP Multi Range Air Velocity Transmitter can simultaneously display and output Air Velocity, Temperature and Pressure (optional). This is the first product to combine all 3 variables in one transmitter making the VTP an exceptional option for multi-variable measuring. The VTP utilizes an industrial 316 Stainless Steel armored RTD sensor as the thermal air velocity measuring component. Using a fully protected 316 SS sensor drastically extends the life of the air velocity sensor and also makes it insensitive to water, dust or corrosion. The VTP comes standard with a LCD and can simultaneously display air velocity, temperature, and pressure. The VTP is easily configured or adjusted in the field with the digital display and keypad. The Air Velocity Range and Pressure Range are both field adjustable as well as units of measure. Other adjustable parameters include signal dampening and low velocity cut off point.
