- Highly accurate and long-term stable ceramic measuring elements
- Electronics versions with HART, IO-Link and Modbus
- ATEX approval
Description
The device Precont® PU4SC is an electronic pressure transmitter / pressure switch for monitoring, control and continuous measurement of pressures.
A high variety of versions of process connections and electronic types allows the use for a wide range of applications, also for demanding measuring requirements.
The front-flush process connection enables the cleanability of the wetted diaphragm to be integrated into the process, also by CIP/SIP cleaning processes.
Low-maintenance and trouble-free pressure measurement is thus also guaranteed in critical applications with viscose or also frequently changing media.
Due to its high accuracy and the digital adjustability by HART®, RS485 Modbus®-RTU or IO-Link® the device Precont® PU4SC can be suited to a wide variety of applications.
The robust design and the high-quality workmanship turns the device into a very high quality product, which even the most adverse environmental conditions cannot affect, whether the lowest temperatures when used outdoors, extreme shock and vibration stress or aggressive media.
A captive laser marking of the type label ensures the identifiability throughout the entire lifetime of the device.
Obviously is the optional marking of a measurement point designation resp. TAG, a customer label or of a neutral type label, of course also per laser marking.
A LABS- resp. silicone-free version, a factory calibration with calibration certificate and a customer specific configuration resp. preset is also optionally available like a material test certificate EN10204 3.1 or a factory certifications for drink water suitability.
Customer specific special versions can be realized short-term on request, e.g. special designs for the process connection or other process materials.
