WNK268 Micro Differential Pressure Transmitter
WNK-268 is composed of stainless steel membrane and fixed electrode, which form a variable capacitance. Capacitance values change along with pressure change. Its unique detection circuit turns change of capacitance to linear direct current signal. Elastic membrane can bear overpressure of 70KPa (both positive and negative), and there will be no damage. The transmitter has been done temperature compensation so as to have developed temperature performance and long-term stability.
WNK-268 can be used for measuring differential pressure and gauge pressure (static state), and translates signal to proportional current signal, outputs 4~20mA current signal. Excitation voltage is 24VDC. WNK268 conforms to intrinsic safety requirement, explosion proof level is ia II CT4, which be applied to environment ith explosion-proof requirement. The minimum pressure range of WNK-268 is 0~100Pa, maximum pressure range is 0~100KPa. Accuracy under room temperature is
±1%FS, temperature compensation range is +5~+65ºC. Through temperature compensation circuit, the temperature influence can be lower than ±0.06%FS/ºC.
With excellent cost performance, WNK-268 has been widely applied to nature gas pipe pressure monitoring, wind pressure monitoring in power plant and etc.
