Installation - Universal Sensor 078

The tekmar Universal Sensors have a brass sleeve for fast response and a wide operating

range. These sensors can be used in a multitude of applications. The 078 is supplied with

15 ft (4572 mm) of two conductor wire.

STEP ONE

MOUNTING THE SENSOR

NOTE: These sensors are designed to mount on a pipe or in a temperature immersion well.

The Universal Sensor can be strapped directly to the

pipe using the cable tie provided. Insulation should

be placed around the sensor to reduce the effect of

air currents on the sensor measurement.

The Universal Sensor should be placed downstream

of a pump or after an elbow or similar fitting. This is

especially important if large diameter pipes are used

as the thermal stratification within the pipe can result

in erroneous sensor readings. Proper sensor location

requires that the fluid is thoroughly mixed within the

pipe before it reaches the sensor.

STEP TWO WIRING AND TESTING THE SENSOR Caution: Do not run sensor wires parallel to telephone or power cables. If the sensor wires are located in an area with strong sources of electromagnetic interference, shielded cable or twisted pair should be used or the wires can be run in a grounded metal conduit. If using shielded cable, the shield wire should be connected to the Com Sen terminal on the control and not to earth ground.
