Explosion Proof Pressure Transmitter 0.1%
Class I Div 1 | Sealed Gauge
AST46HA-Factory-Sealed

AST46HA high accuracy Explosionproof Pressure Transducer/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
- CSA 30 Class 2 Div 1 Groups E, F, G Dust Ignition-proof
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 AST46HA uses a one piece stainless steel sensor to offer continuous operation.



Benefits
- ANSI/ISA - 12.27.01.2003 Certified "Single Seal" (no need for expensive secondary seal)
- ABS (American Bureau of Shipping) Approved
- Excellent Accuracy and Performance over Cold and Hot Temperatures
- High Proof and Burst Pressure
- From 100 to 20,000 PSI (Factory Sealed Gauge)*
- Available in Exotic Alloys (Consult Factory for Inconel 718 or Hastelloy C276)
*For pressures less than 100 PSI, see AST46HA Vented Gauge Pressure data sheet.
