Gauge/relative devices are equipped with cable with
integrated air tube for atmospheric pressure reference.
Install cable end in a control cabinet or suitable terminal
box in dry area which is free of aggressive gasses to avoid
damages.
For the electrical connection a shielded and twisted
multicore cable is recommended.
Removing the protection cap (if necessary)
If the device shall be used in high-viscosity media, a careful
removal of the cap before start-up is necessary (if existing).
To prevent a damage of the diaphragm, please follow these
instructions.
Removal by hand
- Hold the probe in a way that the protection cap points
upwards.
- Hold the probe with one hand on the sensor section (1).
- Remove the protection cap (2) with the other hand.
Removal with a tool (recommended)
- Hold the probe in a way that the protection cap points
upwards.
- Slide a small tool such as a screwdriver (8) straight through
two opposite drill holes in the protective cap (2).
- Lever it off by moving up the handle of the screwdriver.
Make sure that the sensor (7) under the protection cap will
not be damaged!
Separability
(with LMK 358, LMK 358H, LMK 808, LMK 858,
LMP 308, LMP 308i and LMP 808), LCT 307i RS 485
In order to facilitate stock keeping and maintenance, the probe
head is plugged to the cable assembly
with a connector and can be easily
changed.
Disassembly
- Hold the probe on the sensor
section (2) with one hand and turn
the nut (4) carefully to the left with
the other hand. Prevent torsion of
the cable section (3) against the
housing!
- While screwing and pulling off the
sensor section (2) from the cable
section (3), hold it straight to
prevent damages on the plugs.
Assembly
- Check the o-rings (5, 6) and exchange damaged o-rings if
necessary.
- Lubricate the radial o-rings (5) with Vaseline or o-ring
grease.
- Remove any grease residue from the axial-o-ring (6).
- Plug the cable section (3) straight into the plug of the
sensor section (2).
- Hold the probe onto the sensor section (2) with one hand.
Screw on and tighten the nut (4) carefully with the other
hand. Prevent torsion of the cable section (3) against the
housing!
