Setra differential pressure transmitter-Model 268/268 Ex/268Mr Intrinsically safe explosion-proof type
Mode1 268 series micro differential pressure sensor consists of a stainless steel diaphragm and a fixed electrode with a variable capacitance, pressure changes, capacitance value changes. Setra's unique detection circuit converts changes in capacitance values into linear DIRECT current signals. Elastic diaphragm can withstand 70KPa overpressure (positive/negative) without damage. This sensor/transmitter has been temperature compensated for improved temperature performance and long term stability.
Model 268 or 268MR differential pressure transmitters can be used to measure differential or gauge pressure (static) and convert the signal into a proportional current signal, which outputs a current signal of 4-20mA. Excitation voltage is 24VDC. Model 268(EX) meets intrinsically safe requirements and is rated IA LL CT4(optional) for normal operation in explosion-proof environments. The minimum measurement range of Model268/268MR is 0~25Pa and the maximum measurement range is 0~25KPa. The accuracy is ±1%FS at room temperature, and the temperature compensation range is +5~+65°C. Through the temperature compensation circuit, the temperature influence is less than ±0.06%FS/°C.
Model 268/268MR with its excellent performance-to-price ratio, widely used in natural gas pipeline monitoring, power plant wind pressure detection and other fields.
