Description

The ESCP-SAPT Transmitter from ES Systems is an ITAR-free, high-precision pressure transducer designed for space applications. It is ideal for measuring the static pressure of propellant fluids in propulsion systems, including green propellants. Its robust design ensures it can withstand the challenging conditions of space, including extreme radiation and temperature environments.

Key Features

The ESCP-SAPT pressure transmitter integrates a MEMS capacitive pressure sensor and ES Systems' custom radiation-hardened signal conditioning IC. Built from titanium (Ti6AI4V) for a lightweight, compact design, it offers excellent mass optimization (<160 g) and reliability. The transmitter is suitable for both low and high-pressure ranges and is equipped with analog pressure output and temperature readings to ensure precision calibration and temperature compensation.
