Calibration
This transmitter is factory calibrated. The transmitter
should not be calibrated in the field. The only way to
determine if the temperature transmitter is out of
calibration (either span adjust or zero adjust) is with
an accurate two-temperature bath and an accurate
pressure gauge. Span adjustment or zero
adjustment cannot be made in the field because of
the equipment and time required.
Because of variations in lengths of pneumatic
tubing, airflow through restrictors, ambient
temperatures, etc., there will be small errors
between actual temperature at sensing element and
gauge indication. For minor improvements in
accuracy, adjust the pointer on the receiver gauge to
agree with the temperature at the sensing element.
Additional suggestions are given in the Table 3
Troubleshooting Chart.
Preventive Maintenance
The temperature transmitter does not require
lubrication.
Periodically clean dust from the transmitter body
using a soft hair brush.
Check yearly to ensure that temperature at sensing
element agrees with temperature at gauge.
