Flush-Mounted Pressure and Level Transmitter PZT 100/101 Hengesbach

The pressure transmitters PZT are applicable for pressure and level measurements in pipes and vessels. The modular process connection system offers a huge variety of connection adapters and adds a sustainable cost reduction. The flush mounted process connection with its sealing cone free of elastomers and its stainless steel membrane is certified by EHEDG, type EL-CLASS I and hence applicable for measurements with highest hygienic requirements.

The vacuum tight measuring cell with stainless steel membrane works with the piezoresistive measuring principle. The pressure transmitters PZT are designed for measuring ranges of -1/0โ€ฆ0,35bar up to -1/0โ€ฆ100bar. Special measuring ranges are also available. Due to the construction for permanent temperatures up to 125ยฐC or 200ยฐC respectively the transmitter are CIP and SIP cleanable. In addition the high protection classes IP67 and IP69K allow an accurate outside cleaning with foam and power washer and prevent the permeation of humidity into the instrument. As an additional protection against humidity the electronics in the housing are completely casted.

All the pressure transmitters in series 100/101 are designed for universal applications and, in particular, for applications with constantly high temperatures of up to 200ยฐC. Furthermore, using the on-site display with series 100 and the display and operating module OPUSM in series 101, the pressure transmitters can be simply read out, configured and diagnosed.

Features:
