MPT4A Miniature Pressure Transmitter MPT4A

The ICS-NH MPT 4A is a miniature pressure transmitter designed for precise pressure measurement in space-constrained and demanding environments. Its extremely compact form factor, combined with robust stainless steel construction, makes it suitable for integration into systems where size, reliability and performance are critical.

The transmitter supports configurable pressure ranges from 0–30 psi up to 0–3,000 psi, providing flexibility across a wide range of applications. It delivers a ratiometric analogue output (0.5–4.5 V) at a 5 V supply, ensuring compatibility with standard electronic control systems and enabling accurate signal scaling. Built around a thin film stainless steel (17-4PH) pressure sensor with ASIC-based signal conditioning, the MPT 4A offers stable and repeatable performance. It features fast response times (0.1 ms), low hysteresis and excellent repeatability, making it suitable for both static and dynamic measurement applications. The integrated electronics provide reverse polarity protection, short-circuit protection, EMC/ESD robustness and high voltage protection up to 33 V, ensuring reliable operation in electrically demanding environments.
