Ametek 831 Fixed Range Pressure Transmitter

Ametek - U.S. Gauge

831 Fixed Range Pressure Transmitter

Pressure Measurement

Description - The Model 831 transmitter is weatherproof and capable of a direct spray with forces up to 200 psi without internal leakage.

The Model 831 (standard and low power) has FM and CSA explosion-proof ratings. The 831D (differential pressure) also carries the CSA explosion-proof rating. All Model 831s meet NACE standards for offshore applications.

The standard Model 831 and the Model 831D feature a 4 to 20 mA output standard with a 12 to 30 VDC power supply. The Model 831 Low Power provides a three wire 1-5 or 0.8-3.2 voltage output and requires less than 30 milliwatts of total power to operate.

The combination of low power requirement, small size, excellent performance and low price make the Model 831 Low Power Transmitter ideal for critical outdoor applications. This model requires 6 or 8-14 VDC excitation and is available in pressure ranges from 15 to 5000 psi.
