SEAT SETRA Micro Differential Pressure Transmitter 261C

SEAT SETRA Micro Differential Pressure Transmitter 261C

The Model 261C series micro differential pressure sensor is designed for HVAC applications. It adopts Setra's variable capacitance technology, which consists of a stainless steel diaphragm and a gold-plated ceramic fixed electrode to form a variable capacitance. When the pressure changes, the gap between the two plates changes, causing the capacitance value to change. Setra's detection circuit converts changes in capacitance values into linear DC electrical signals.
The Model 261C series inherits Setra's traditional features of precision, fast response, and low range. Considering the requirements of pharmaceutical factories and clean rooms for micro differential pressure transmitters, on-site LCD display meets the requirements of industry applications and is the choice for pharmaceutical factories, electronic clean rooms, and dust-free laboratories.

The Model 261C micro differential pressure transmitter can be used to measure differential pressure or gauge pressure (static pressure), and can choose output signals of 4-20mA, 0-5VDC, or 0-10VDC. The Model 261C sensor/transmitter has been temperature compensated with an excitation voltage of 24VDC. For voltage signal products, a 24VAC power supply can also be selected. The minimum measurement range of Model 261 is 0~25Pa, with a standard accuracy of ± 1% FS at room temperature. The temperature compensation range is+5~+65 ℃, and the temperature effect is reduced to less than ± 0.06% FS/℃ through a temperature compensation circuit.
Model 261 has a high cost performance ratio and is widely used in pharmaceutical workshops, clean electronic factories, and infectious disease wards.
