Industrial OEM Pressure Transmitter
Quick Specs...
- Sensing Ranges from Vacuum to 10,000 psi
- Rugged Stainless Steel & Valox® Housings
- Ideal for High Shock & Vibration Applications
Overview / Design Principle:
The 809 series pressure transmitter is designed specifically for industrial applications with demanding price and performance requirements. They offer exceptional reliability in typical industrial grade environments. The 809 series pressure transmitter operates on low-cost, unregulated DC power, and over a wide temperature band with both liquids and gases. Designed for harsh environments, they are suitable for use in high shock and vibration applications. Stainless steel and Valox® housings are small and lightweight for easy integration into compact systems. The standard feature set of the 809 Series delivers exceptional performance in extreme environmental conditions at a price that OEMs will appreciate.
How they Operate:
809 Series transducers utilize a proven center mount electrode configuration combined with a durable 17-4 PH stainless steel pressure sensing element to form a variable capacitor. As pressure (or vacuum) increases or decreases, the capacitance changes. Self-contained high-level output IC-circuitry converts the change in capacitance to a fully conditioned linear voltage or current output signal.
