OBS-LE Digital Pressure Transmitter

The OBS-LE Series is the industry’s only integral molded one-piece plastic Pressure Transmitter and Gauge Guard. 

Gauge Guards are utilized to protect the pressure gauge from any corrosive media in the process system via an isolator. 

The OBS-LE Series Pressure Transmitters are truly unique and industry leading when it comes to pressure measurement in corrosive environments. 

OBS-LE Pressure Transmitters are a one-piece design and come factory pre-filled, resulting in an industry leading accuracy of 1.0%.

Eliminating the need for filling saves the user time and the difficulty of having to fill a gauge isolator. 

The bright LED will change from green to red in any upset condition. 

The OBS-LE is equipped with a 4-20mA output + 2 Relays (NPN or PNP). 

The OBS-LE Series is available in PVC, PP & PVDF, all equipped with a Teflon® Diaphragm, making the entire unit completely corrosion resistant and the perfect pressure gauge for chemical applications. 

Engineering the entire body in a plastic housing rather than just the gauge guard allows users to be confident that the complete unit will stand up in even the most corrosive environments.
