INTERCHANGEABLE SENSOR ARRAYS
Each sensor array contains a precision voltmeter. The calibration can therefore be done without the main E-Val Pro device, which continues to be at disposal during this time.
SENSOR ARRAYS FOR THERMOCOUPLES
Each of the interchangeable sensor arrays can accomodate up to 12 thermocouples or analog / digital inputs for a total of 40 channels per E-Val Pro device. The sensor arrays with 4 or 12 channels can accomodate thermocouples type T and K (prepared for type J, B, E, N, R and S),
SENSOR ARRAYS FOR ANALOG / DIGITAL INPUTS
Multifunction sensor arrays designed for Ellab pressure and humidity sensors, 4-20 mA, 0-10 V inputs and I/O relay.
INTELLIGENT SENSOR CONNECTORS
Ellab has developed intelligent sensor connectors in the form of USB plugs. Ellab thermocouples are firmly connected to the plug which is molded and sealed. For the use of own thermocouples, USB connectors with screw terminals are available.
COLD JUNCTION CKOMPENSATION FÜR THERMOCOUPLES
The sensor plugs have the design of a USB plug. The connectors for thermocouples have a Pt1000 sensor installed for the cold junction compensation.
MEMORY FOR CALIBRATION OFFSETS AND SERIAL NUMBER
A in the connector built-in EEPROM allows to store calibration offsets and a serial number of each thermocouple. If a thermocouple is defective, it can be replaced against another, pre-calibrated thermocouple, making a re-calibration unnecessary.
