Pressure and level transmitters

Pressure transmitters convert the pressure of a gas or liquid into a standard signal such as 4 to 20 mA, 0 to 10 V or RS485. DWIN supplies gauge, absolute and differential pressure transmitters, submersible level transmitters, pressure switches and OEM pressure sensor cores.

What is the difference between a pressure sensor and a pressure transmitter?

A pressure sensor produces a small raw signal from its sensing element. A pressure transmitter adds the electronics that compensate, calibrate and convert that signal into a standard output such as 4 to 20 mA for a control system.

How does a submersible level transmitter work?

It hangs at the bottom of a tank or well and measures the hydrostatic pressure of the liquid above it. Pressure rises in proportion to depth, so the transmitter outputs liquid level directly; a vented cable references it to atmosphere.
