AST4400 Hammer Union Pressure Transducer

Brand: American Sensor Technologies Inc
Request Information Favorite
The Hammer Union pressure transmitter is a US manufactured pressure transmitter with WecoTM process connections.

Offered with 4-20mA output signals, this design features high shock and vibration resistance, with testing up to 1,000G. Pressure is measured from an Inconel® 718 sensing element using MEMS silicon based strain gauges to produce accurate repeatable measurements. 

The cage design allows for protection of both the connector and mating connector. The modular enclosure allows for simple factory replacement of the transmitter at a fraction of the cost of the whole assembly.
