The TPM series is ideal for applications in hydraulic and pneumatic systems, as well as for fuel and lubricant pressure sensing, leak detection, filter testing, and tank level sensing. These demanding requirements can be found in many industries, including chemical plants, mining, power generation, plastics manufacturing, water treatment plants, and agriculture.
The TPM series transmitters offer a 4-20 mA output proportional to the pressure detected directly by a four-arm bridge with an active probe. This probe is formed from highly stable resistors fused to a high-purity ceramic pressure-sensing element. Internally, the electronics comprise a main signal processing module using a high-speed ASIC-based digital signal processor and a separate board handling the interface and EMC immunity and emissions requirements. During manufacturing, the sensor can be individually or batch-treated depending on customer performance requirements and individual calibration. All TPM elements are combined to ensure ±0.1% nonlinear span, hysteresis specification, and repeatability (BFSL) across the entire operating temperature range, along with excellent long-term stability (±0.1% span/12 months typical).
Featuring a stainless steel housing, the robust construction of the TPM series transmitters is complemented by a selection of pressure ports and electrical connections. The family supports probe, sealed probe, absolute pressure, and composite pressure options, offering 18 pressure ranges from 0-100 mbar to 0-600 bar. Additional options allow for different sealing materials and connection types, including EPDM for potable water applications. Custom calibration is also available.
