Gefran TSA Pressure Transmitter

The Gefran TSA is a pressure transmitter designed for low and medium pressure ranges, utilizing a silicon piezoresistive element in a Wheatstone bridge configuration. It is primarily used in industrial refrigeration, HVAC, compressors, pumps, air filtration, packaging, and general pressure monitoring applications.

Technical Data

  • Measuring ranges: 0…0.05 to 0…60 bar
  • Available absolute ranges: from ≥1 bar abs
  • Barometric range: 0.8…1.2 bar abs
  • Accuracy: ±0.15% FS typical, ±0.5% FS for absolute ranges
  • Overpressure: 4x…2x, depending on range
  • Burst pressure: 6x…3x, depending on range
  • Response time: <4 ms
  • Process temperature: -20…+85 °C
  • Protection: IP65/IP67 with correctly installed female connector

Materials and Media Compatibility

Body is AISI 304; wetted parts include AISI 316L. Product documentation also lists NBR, Viton and silicone oil fill. Media compatibility must be verified for refrigerants, air, water, technical gases, or light industrial fluids.

Outputs and Connections

Analog outputs available: 4…20 mA, 0…10 Vdc, 0.1…10.1 Vdc, 0…5 Vdc. 4…20 mA is preferred for long cable runs to PLC/BMS. Voltage outputs are used for short distances and HVAC/machine controllers.

Process Connections

Standard process connections: G 1/4 gas male DIN 3852-E, G 1/2A DIN 16288. Electrical connections: M12x1, EN 175301-801 type A/C, or shielded cable.

Installation

Transmitter body must be grounded via the machine. Use shielded cable; connect shield at connector side only, leave open at PLC/instrument side. Signal cables should be routed separately from power cables.

Standards

TSA declaration of conformity references RoHS 2011/65/EU, EMC 2014/30/EU, EN 50581:2012, EN 61326-1:2013, EN 61326-2-3:2013.
