QW3151DG Explosion proof Direct Mounted Negetive Pressure Transmitter with output 4-20mA

Direct mount pressure transmitter QW3151DGP select high-precision, high stability and high reliability diffused silicon pressure sensing element and

imported high-quality integrated circuits, which is a high precision, reliable, good stability, long service life industrial pressure

transmitter for measuring the liquid level of the liquid or gas pressure, and a variety of liquid. Live remote

pressure and level measurement instrumentation and converted into a standard electrical signal pressure or

level. QW3151DGP pressure transmitter, because of its excellent performance, instead of imported high-grade pressure transmitter for high measurement precision measurement and control requirements of the

occasion, compact structure, light weight, three buttons can be used on-site free configuration.
