Designed for many markets/applications
Senex’s DP Series differential pressure transmitter is designed for End Users and OEM ‘s where ruggedness, high performance, and reliability are required at a competitive price. This product is modular and is configurable to meet our customers exact needs.

Manufactured for extended life cycle
 Every DP Series is built using advanced manufacturing techniques to ensure symmetry between the Hi and LO ports. Symmetry, along with automated welding procedures and extreme environmental burn-in give Senex’s differential pressure products excellent performance and reliability over time and at high elevated line pressure.

Entirely welded 316L SST pressure cavities
The DP Series pressure ports all welded 316 SST ‘O’-Ring free design make it ideal for high cyclical applications, capillary filled systems, or applications where a guaranteed leak free system is needed.
