Setra 265 Very Low Differential Pressure Transducer

Setra’s Model 265 Pressure Transmitter measures differential or gauge pressure and converts this differential pressure into a proportional electrical signal output. The 265 Series voltage outputs are available with 24VAC excitation and are available in 4-20mA, 0-5VDC, and 0-10VDC outputs.

Model 265 differential pressure transmitters range from 0 to 50 Pa to 0 to 25 KPa. In a normal temperature environment, the accuracy is ±1% of full scale. In the temperature range of -18 ° C ~ +65 ° C, the temperature effect is less than ± 0.06% FS / ° C. Model 265 Series Differential Pressure Transmitter utilizes advanced all-stainless steel elastic diaphragm technology. The stainless steel diaphragm and the fixed electrode form a variable capacitor. When the pressure changes, the capacitance value also changes. Setra’s unique detection circuit converts changes in capacitance values ​​into linear DC signals. The elastic diaphragm can withstand 70KPa overpressure (both positive/negative) without damage.

This sensor/transmitter has been temperature compensated for improved temperature performance and long-term stability.
