Pressure transmitter range for hydraulic, pneumatic applications
TT Electronics’ TPM Series of industrial pressure transmitters have an operating temperature range from -20 to 125 C and are designed for hydraulic and pneumatic system applications as well as fuel and lubricant pressure sensing, leak detection, filter testing, and tank level sensing applications. The TPM Series transmitters deliver a 4 to 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 utilizes an ASIC-based high‑speed digital signal processor and a separate board that handles the interface and EMC immunity and emissions requirements.
All elements of the TPM are designed to ensure a ±0.1% span non-linearity, hysteresis, and repeatability specification over the full operating temperature range together with excellent long-term stability. 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.
