Differential pressure transmitter / pressure transmitter price FS300 smart capacitive pressure (gauge pressure) / differential pressure transmitter absolute pressure, including the 3151 metal capacitive intelligent transmitter, differential pressure smart transmitters 3151, 3151 Metal capacitive analog transmitter, 3151 capacitive intelligent transmitter 3151T metal straight-fit Intelligent loose and 3151T straight mounted analog transmitters. Is the atmospheric pressure (or vacuum) is measured pressure signal reference terminal, only one port and process piping. Direct or indirect effect works when the pressure in the measuring diaphragm surface of the diaphragm produce small deformation, high-precision measurement circuit diaphragm on this tiny deformation converted into a voltage signal proportional to the pressure, temperature-pressure compensation, then using a dedicated chip to the voltage signal is converted to industry standard 4-20mA current signal or voltage signal 1-5V. Since the measuring diaphragm integrated circuit, comprising linear and internal temperature compensation circuit, it is possible to achieve high accuracy and stability, facilitate a variety of complex industrial environment field use. As a result of the microprocessor leaving flexibility increases, enhancements; has a strong self-diagnostic capabilities; zero and span adjustments affect each other; both remote and local sound settings, calibration function; two-wire, HART protocol HART protocol can communicate with the terminal without interrupting the output; compensation for the use of digital technology to compensate for temperature and static pressure; good stability, high precision, adjustable damping, anti-overload strong unidirectional; no mechanical transmission parts, repairs work less, rugged anti-vibration; all common parts, easy maintenance; optional diaphragm material contact with the media, all-weather use; FS300 smart capacitive pressure / differential pressure transmitters square construction industry equipment (Shanghai) Co., Ltd. __ _ differential pressure transmitter / pressure transmitter price
