Pressure and Level Transmitter PZT 200/201 HengesbachIndonesia Industrial Parts

The PZT pressure transmitters are suitable for taking pressure and filling level measurements in pipelines and containers. The modular process connection system offers a wide range of connection adapters and helps to cut costs in the long term. The flush-mounted process connection with an elastomer-free sealing cone is predestined for measurements that satisfy even the most stringent hygiene requirements.

The vacuum-proof measuring cell with stainless steel membrane works on the basis of the piezoresistive measuring principle The PZT pressure transmitters are designed to measure from -1/0…0.35 to -1/0…100bar. Special measuring ranges are also available on request. Given the nature of the design for long-term medium temperatures of up to 125°C / 200°C, CIP and SIP cleaning methods can be used on the transmitters.

The high protection classes of IP67 and IP69K also mean that the devices can be safely cleaned on the outside with foam and a high-pressure cleaner and that moisture is reliably prevented from entering the device.

All the pressure transmitters in series 200/201are highly precise and have been developed for difficult tank content measurements and, in particular, for applications with constantly high temperatures of up to 200°C. Furthermore, using the on-site display with series 200 and the display and operating module OPUS I in series 201, the pressure transmitters can be simply read out, configured, and diagnosed. With the EASY TRANSFER function, the configuration data can be copied via the OPUSi module onto other pressure transmitters in series 201. This makes commissioning easier for the same applications. The option of programming in tank dimensions for standard tank designs as well as for special tanks using the volumes calculated by means of volumetric measurement means exact filling levels and tank content can be shown directly. In addition to the features of the 200/201 series, the pressure transmitters in the 200H/201H series boast an integrated HART®
modem. This also enables remote configuration and evaluation of the transmitters using the HART® protocol.

Electrical Connection: The standard electrical connection is via a cable screw connection M16x1.5. On removing the device lid, the connection is created using screw terminals.
