Pressure-Tight Installation - E+E Elektronik HTS801 User Manual

4.4.2. Pressure-tight Installation
For pressure-tight installation up to 20 bar (300 psi) a pressure-tight feedthrough is available as an accessory
(see chapter 8.Spare.Parts / Accessories).
WARNING
General safety instructions for pressure-tight installation
The installation, commissioning and operation of the HTS801-T7 may be performed by qualified staff
only. Special attention shall be paid to the correct installation of the probe into the process. In case of
inappropriate installation there is the risk for the probe to be suddenly expulsed due to the pressure in the
process.
Bending over the sensing probe should be avoided under any circumstances!
Make sure that the surface of the probe is not damaged during installation. A damaged probe surface may
lead to damaged seals and consequently to leakage and pressure loss.
The probe is rated with leakage rate B according to EN12266-1.
CAUTION
Safety instructions for pressure-tight feedthrough:
Do not assemble the probe and tighten the feedthrough if the plant is under pressure.
The plant must not be vented by releasing the nut (A).
Use appropriate seal on conical probe threads.
Never rotate the screw connection body (B) but hold the screw connection body (B) securely and turn the nut (A).
Avoid unnecessary disassembly of pipe screw connections.
Position the cut in fitting >75 mm (2.95") from the end of the filter cap to the end of the fitting!
For a probe length of 65 mm a cut in fitting is not possible.
