5.4.7 Mounting the instrument

Prior to commissioning, the submersible pressure sensor must be subjected to a visual inspection.
Leaking fluid is indicative of damage.
■
Only use the submersible pressure sensor if it is in perfect condition with respect to safety.
■
The protection cap protects the internal diaphragm from damage during transport and during the lowering of the probe.
With viscous or contaminated media, the protection cap can be removed in order to ensure trouble-free operation.
When laying the cable, a minimum bending radius of 120 mm must be ensured.
