Pneumatic connections
The air supply (A) and output (U) are threaded 1/4 inch NPT internal. It is important that the air
supply is clean, dry and oil-free. All air lines connections should be checked to ensure that the are
free from leaks. For the reduction to 1.4 bar employ an airfilter- regulator with an output gauge.
Before connecting the controller purge the supply line.

Temperature
- Install the bulb as shown in figure.
- Assure full immersion in the process of the sensing part of the bulb.
- Do not overrange the instrument.
- Do not use a naked flame to heat the bulb.
- When thermowells are used, we suggest to apply a thermal heat transfer media
(liquid or metal powder) according to the temperature range.
- The radius for bending the capillary must be 25 mm minimum ( Suggested: 50 mm)
- Avoid stressing the capillary during and after the installation.
- If the capillary is plain avoid courses with high temperatures (max. 60 °C)
- Do not cut the capillary tubing.
