4.1 Description

The Pascal ET is professional advanced superior calibrator of latest generation. User-friendly interface by a wide display with
EN
an industrial touchscreen through which it is possible to manage the instrument completely.
The operations are simplified thanks to the touchscreen:
The display changes in a dynamic way according to the user selections, following test by step the operator during the
calibration process, decreasing the learning time and the human errors.
The touchscreen can be operated by nude or gloved hands:
Dirty parts can be easily removed with a cloth or a sponge. The touchscreen can be locked during the measurement process
to avoid unintentional pressing of buttons.
The backlight illumination with LED guarantees a perfect view in case of low environmental visibility.
Five buttons are present beside the touchscreen:
Turn on/off of the instrument
■
Home function
■
Programmable function
■
Changing the number of windows
■
The electrical part consists from two until four electrical modules to be selected between the available ones (2 inputs (IN) – 2
outputs (OUT) – one HART
The Pascal ET consists of two parts: pressure part and electrical one.
The pressure part consists of one or two connectors for connecting the external pressure sensors:
Pneumatic distribution block
■
Internal manual vacuum/pressure generators with fine adjustment
■
Up to four internal pressure sensors with overpressure valves.
■
The electrical part consists of up to four electrical module (2 inputs (IN), 2 outputs (OUT) and a HART
measurement and generation of mA, mV, V, Hz, Ω, Pulse, TC/RTD.
On the side panel of the instrument there are several connectors for:
Recharging the battery
■
RS-232 interface
■
Connection to the external pressure sensors
■
Connection for the environment parameters (temperature, humidity and atmospheric pressure)
■
Moreover there are the connections to provide DC 24 V power supply to the test item.
The Pascal ET is powered with an internal battery pack. The battery allows 8 hours of standard operation before recharging.
Operating Pascal ET user is able to calibrate the whole industrial instrumentation like for example:
Electronic and pneumatic pressure/vacuum transmitter
■
Electronic and pneumatic differential pressure transmitter
■
Electronic and pneumatic temperature transmitter (thermocouple and RTD)
■
Signal converter V, mV, mA, Hz, Pulse, Ω
■
Signal converter I/P and P/I
■
Signal isolator mA, mV
■
Mathematical instrument (adder, subtractor, multiplier, divider)
■
Manometer, pressure switch
■
Temperature monitor switch
■
Thermocouple and resistance thermometer
