AST46PT-Vented

Vented Gauge | ASIC | CSA Approved Explosionproof Pressure/Temperature Transmitter

AST46PT high accuracy Explosionproof Pressure/Temperature Transmitter is CSA approved for use in hazardous areas including:

  • CSA 30 (UL1203/FM3615) Class 1 Zone 1 Group IIC
  • CSA 30 Class 1 Div 1 Groups A, B, C, D Explosionproof
Applying digital compensation, this product offers top performance over a wide temperature range. Utilizing Krystal Bond Technology™, the sensing element will measure pressure in the most extreme temperature conditions. Where other sensor technologies will freeze or boil, the AST46PT uses a one piece stainless steel sensor to offer continuous operation.
