38. 5 Sensor Installation Guidelines Proper sensor installation can eliminate many problems in a control system The probe should be placed so that it can detect any temperature change with minimal thermal lag In a process that requires fairly constant heat output the probe should be placed close to the heater In a process where the heat demand is variable the probe should be close to the work area Some experiments with probe location are often required to find the optimum position In a liquid process the addition of a stirrer will help eliminate thermal lag Since a thermocouple is basically a point measuring device placing more than one thermocouple in parallel can provide an average temperature readout and produce better results in most air heated processes The proper sensor type is also a very important factor in obtaining precise measurements The sensor must have the correct temperature range to meet the process requirements In special processes the sensor might have additional requirements K E Consideration should be given to pre vent unauthorized personnel from gaining access to the power terminals such as leak proof anti vibration antiseptic etc Standard sensor limits of error are 4 F 2 or 0 75 of sensed temperature half that for special plus drift caused by improper protection or an over temperature occurrence This error is far greater than controller error and cannot be corrected on the se
