Type ELH102 Wide Angle Sensing Head

The Type ELH102 Wide Angle Sensing Head is a robust inclinometer unit with a die cast Aluminium housing which is sealed to IP65. The plastic multipole connector is rated IP68.

The angle reading is available at the output connector in various forms to suit different applications.
For example the output can be
    analogue current     4-20mA;     for driving long cables
    analogue voltage     2.0 Volts    for general purpose use
    digital serial output    for input to computer systems
The digital output at RS232 /RS485 levels consists of a synchronising ASCII character followed by the measured angle as a series of ASCII coded numbers.
The data is continuously transmitted while the device is powered up.
Alternative output coding is available to special order.

To achieve the highest specifications the system monitors the temperature of the sensor, and uses the result to correct for zero drift and scale drift.
For optimum performance the sensor should thus be in thermal equilibrium with its surroundings


The unit is available with a variety of full scale ranges and accuracies, please contact our engineers for further information.
