WARNING
General safety instructions for pressure-tight installation
The installation, commissioning and operation of the HTS801-T9 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.
