Digitally compensated pressure transmitter range provides high performance with multiple configuration options

Written by: Tom Austin-Morgan | Published:

TT Electronics has introduced its versatile TPM Series of high-performance industrial pressure transmitters. Featuring digital compensation to provide accurate, reliable pressure measurements with excellent long-term stability over a temperature range from -20 to 125°C, the TPM Series is suited for applications in hydraulic and pneumatic systems, and for fuel and lubricant pressure sensing, leak detection, filter testing and tank level sensing. These demanding requirements can be found in many different industries from chemical plants, mining and power generation to plastics manufacturing, water treatment plants and farming.

TPM Series transmitters deliver a 4-20mA output that is proportional to the pressure directly detected by a four-arm, active strain-gauge bridge that is formed from highly stable resistors fused to a high purity ceramic pressure-sensing element. Internally, the electronic elements comprise a primary signal processing module that utilises an ASIC-based high‑speed digital signal processor and a separate board that handles the interface and EMC immunity and emissions requirements.

Featuring a stainless steel housing, the rugged construction of the TPM Series transmitters is complemented by a choice of pressure ports and electrical connections. The family supports options for gauge, sealed gauge, absolute and compound pressure types and offers 18 pressure ranges from 0-100 mbar to 0-600 bar. Further options allow for different pressure connection materials and seal types, which include EPDM for portable water applications.
