Model 831 Explosion Proof Pressure Transmitter

Brand: AMETEK, Inc
Request Information
Does not ship to United States
Our model 831 is an explosion-proof fixed range pressure sensor available in differential pressure, low power, or standard pressure versions.

The Model 831 pressure transmitter is the most durable, accurate and cost effective fixed range transmitters on the market with an all welded 316 stainless steel construction and wetted parts.

Known for years of stable performance in even the toughest environmental and corrosive media conditions. This transmitter is weatherproof and capable of a direct spray with forces up to 200 psi without internal leakage.

The 831 is available in pressure ranges from 6 psi to 5,000 psi, or differential 6 psid to 500 psid.

The accuracy of the Standard and Low Power units is ± 0.3% full scale including linearity (BFSL) and the Differential unit is ± 0.5% full scale including linearity (BFSL).

The small size and light weight of the Model 831 transmitter eliminates the need for complicated mounting hardware and mechanical supports, reducing installation time.

The in-line connection permits simple field wiring without the need for additional hardware, adding to speed and ease of installation.

The Standard and Differential versions are available with 4-20 mA output. The Low Power version is available with an input of 8-14 VDC or 6-14 VDC with an output of either 1-5 VDC or 0.8-3.2 VDC.

The combination of the low power requirement, small size, excellent performance and low price make the Model 831 Low Power Transmitter ideal for critical outdoor applications that run on battery or solar power.

All models of the 831 pressure transmitters are manufactured in the USA.
Features
  • Available in differential pressure, low power or standard version
  • All welded 316L stainless steel construction and wetted parts
  • 3/4 inch NPT female conduit connection cable
  • 1/2 inch NPT female pressure port, 1/2 inch NPT male, 1/4 inch NPT male
