Intrinsically Safe Pressure Transmitters

AST4400 pressure transmitters are manufactured to meet UL/cUL 913 Class I Division 1 Intrinsically Safe Groups C and D. Available in 316L, Inconel 718, and 17-4 PH stainless steel material, the AST4400 pressure transmitter can meet customer requirements for a variety of liquids and gases from 25 PSI (2bar) up to 10,000 PSI (700 bar).

AST4500 / AST4510 - For submersible level sensors as low as 0-1 PSI (27.68 inches of water column), look no further than the AST4510. It features stainless steel and Hytrel wetted materials, low measurement ranges, and the best price to performance in the industry. The AST4500 is used for pressure ranges above 15 PSI. Both products can be used in liquids requiring intrinsically safe approvals when installed with an approved barrier.

AST4520 - Certain liquids can have a viscous consistency in which traditional level sensors become clogged. AST4520 level sensors provide a flush diaphragm protected by a weighted cage, to continuously monitor level in applications such as wastewater, grease, and lubrication tanks.

AST4520 - Non-Clogging Level Sensors

AST44LP - For low pressure measurement in intrinsically safe areas, the AST44LP is a compact, low cost solution. Measuring from 1 PSI up to 15 PSI, the AST44LP is available in voltage and current output signals for complete flexibility. From external tank monitoring to low pressure gas systems, the AST44LP is an accurate sensor solution.
