Pressure Measurement & Control


High performance pressure ­transmitter

March 2017 Pressure Measurement & Control

Kobold’s PAS pressure transmitter enables precise monitoring of absolute and gauge pressures. The PAS is a microprocessor-based, high performance transmitter, which has a flexible pressure calibration and output signal. It has automatic compensation for ambient temperature and process variables. Communication with the instrument and configuration of various parameters is possible via HART protocol. The PAS loads, modifies and stores all data in EPROM. The device has different measuring ranges between –1...1,5 bar and 0...600 bar and can be used for a multitude of applications.

The heart of this robust and long-term stable measuring instrument is a piezo-resistive pressure sensor. The accuracy is ±0,075% of the calibrated span and process temperatures range from –40 to 120°C. Matching connections allow easy and quick installation and an extensive range of accessories is available. These include various types of diaphragm seals, which may be connected directly or via capillary tube for process temperatures up to 350°C as the application demands.

The measuring process is monitored and evaluated using a high quality microprocessor. This includes the automatic compensation of ambient temperature and process variables; sensor calibration and zero-point adjustment, filtering and damping; continual self-diagnosis and adjustment as well as data transfer; and a clear, freely configurable built-in LC-display. The pressure transmitter has a 2-wire 4–20 mA analog output. Operation and integration into automation systems can also take place using the HART protocol. The protection class is IP67. For hazardous areas the pressure transmitter is available with ATEX Exd approval.
