Product Description

Stainless Steel, Explosion-proof, Accuracy ±0.30%, 4-20 mA or 1-5 VDC Signal

The Series 636 Pressure Transmitter is a low cost, fixed range, stainless steel transmitter with ±0.30% accuracy. It is designed to continuously measure pressure for years in even the toughest environmental and media conditions. Select from 4 ranges to 0-300 psig (0-20 bar) with choice of 4-20 mA output (Model 636) or 1-5 VDC output (Model 636LP). Transmitters are explosion-proof, (FM approved) and meet NACE standards for off-shore applications.

Product Applications

  • Off-shore
  • Process applications
