General

Due to its versatility the hand-held multifunction calibrator Pascal series is ideally suited for on-field testing and calibration of industrial measuring instruments. The typical application is the calibration of pressure transmitters, temperature transmitters, pressure gauges, temperature probes and other measuring instruments. The calibration data are stored in the instrument’s memory. The communication with a PC is used to remotely control the unit and to download the calibration reports.

The Pascal ET is the most advanced portable multifunction calibrator for the measurement and simulation of the following parameters: relative and absolute pressure, electrical signals (mA, mV, V, ?), temperature (TC, RTD), frequency and pulse. In addition, there is the possibility to include an optional HART® module which allows communication with HART® instruments.

Features

The calibrator Pascal ET has a new large colour touchscreen display with a new intuitive and user-friendly interface, that allows an easy and fast configuration of the calibrator. The availability of ATEX approval II 2G Ex ib IIC T4 Gb - Tamb: -10 ... +50 °C expands the possible applications of this calibrator into hazardous areas (only for Pascal ET/IS). Even in the ATEX version the DC 24 V voltage supply for external transmitters is available.

The calibrator has four measurement channels and is thus capable to carry out up to four simultaneous measures. For more flexibility on on-field calibrations, the Pascal ET has an on-board memory for data storage that allows the evaluation of logged measuring values and calibration reports. In laboratory applications the real-time communication allows the remote control of the Pascal ET from a PC.

The Pascal ET can be modularly configured with up to two input and two output modules as well as one HART® module and one output module, which are galvanically isolated from each other. The measurement/simulation of the electrical signals or temperature as well as up to two external pressure sensors enables the operator to configure the calibrator according to his specific requirements. The environmental parameters module (option) is another plus of Pascal ET, it allows the monitoring of the barometric pressure, the ambient temperature and the relative humidity. The values will be stored in the calibration report.
