A pressure transmitter works by converting the physical pressure of a gas or liquid into a standardized electrical signal (most commonly 4–20 mA, often with HART or MODBUS on top). In most industrial designs, the process pressure deflects a metal diaphragm, that force is transferred to a sensor element (often piezoresistive), and onboard electronics linearize, temperature-compensate, and scale the signal to the chosen output.   What a pressure transmitter is doing in one sentence  Pressure → diaphragm movement → sensor changes electrically → electronics correct + scale → output signal.  That’s the core principle whether you’re measuring gauge pressure,

A differential pressure (DP) level transmitter measures liquid level by sensing the pressure at the bottom of a vessel and subtracting the pressure at the

Pressure transmitter accuracy describes the maximum expected deviation between the pressure value the transmitter reports and the true process pressure, usually expressed as a percentage

A high-temperature pressure transmitter is a pressure sensor built to read hot media (typically ~120–150 °C) while protecting its electronics and accuracy; in Pondus Instruments’

To calibrate a pressure transmitter: isolate it from the process, vent and equalize pressure, apply the lower-range pressure (LRV) and set zero, apply the upper-range

A differential pressure (DP) transmitter is an instrument that measures the difference between two pressures (high side “+” and low side “–”) and converts that

A flow transmitter measures how much fluid is moving through a pipe by sensing a pressure-based signal—most commonly the differential pressure (ΔP) created by a

Core principle  At the heart of most industrial transmitters is a piezoresistive bridge bonded to a diaphragm system. Process pressure acts on a thin metal

A pressure sensor is a device that detects and measures the pressure of gases or liquids, converting this pressure into an electrical signal that can

What is a sensor?  At its core, a sensor senses a change in a process variable (e.g., pressure) and produces a proportional electrical signal, such
