Hengesbach Pressure and Level Transmitter TPF0505D Series

The TPF050D pressure transmitter is suitable for measuring of the pressure and filling level in pipes and tanks, even with small nominal diameters. Depending on the process connection, the flush-mounted measuring cell with stainless steel membrane enables measuring ranges of -1/0…0.35bar to -1/0…100bar. The robust stainless steel field housing and the checked protection classes IP 67 and IP 69K withstand all aggressive and residue-free cleaning procedures such as those required in the food and pharmaceuticals industry.

The 050D series pressure transmitters are equipped with a micro-processor controlled electronics system and an accuracy of ≤ ± 0.2% FS. They are parametrised with a simple and user-friendly operating concept via 2 keys and a multi-colour status LED. A TurnDown of up to 4 can be set using the full and empty adjustment. A wide range of hygienic and non-hygienic process connections is available for the TPF050D. The process connection adapters available include: ISO 228 G1“ screw-in threads with an elastomer-free sealing cone and press screw, conical couplings or DIN 11851, VARIVENT^® with Ø 50mm or Ø 68mm, DRD. Customer-specific solutions are also possible.

Features:

• output signal 4...20mA, TURNDOWN 4
• accuracy ≤ ± 0,2%FS
• simple calibration, even without disconnection of the transmitter, through switchable power supply plant / calibrator supply
• with hygienic and standard process connections as a fixed connection
• simple parametering via 2-key concept and multi-colour status-LED
• vacuum and overload safe
• for measurement of pressure and filling level in tanks and pipes with basic requierments
• easy to clean and high protection classes IP 67 und IP 69K
