3. Installation & Operation
3.1 General Requirements
When the sensor is received, check the completeness.
To identify the electrical and pressure connections, refer to the product datasheet or, if applicable,
the specification drawing.
Do not use force when installing the sensor. Use only a wrench on the sensor’s hexagonal flats
to tighten the sensor.
The ambient temperature and the process media to be measured must not exceed the ranges
specified in the sensor specification.
Do not use the sensor where the pressure medium may freeze. This may cause damage to the
sensor and connected pressure equipment.
The materials used for the primary enclosure and pressure bearing surfaces are identified in the
product datasheet or, if applicable, the specification drawing. Make sure that the materials are
applicable for the installation.
Before using the equipment, remove the plastic/rubber protection cap from the pressure
connector.
Some models feature a white PTFE vent filter in the wall of the enclosure. Make sure the vent
filter is correctly installed and is flush with the enclosure body.
3.2 Safety Measures
The operation of sensors in systems whose pressure may exceed the overload values specified
in the data sheet or customer-specific specification drawing is not allowed.
Connection and detachment of sensors from the mains supplying the pressure of the medium to
be measured must be done after the shutoff valve is closed from the process and the pressure in
the working chamber is made equal to atmospheric.
The connecting pipes must have a one-way slope (not less than 1:10) from the pressure collection
point up to the sensor, if the medium to be measured is gas, and down to the sensor if the medium
is liquid. If this is not possible, when measuring gas pressure at the lower points of the connecting
lines, it is necessary to install sludge vessels, and when measuring the liquid pressure at the
highest points, install gas collectors.
Selected devices for mounting sensors should be mounted on straight sections, at the maximum
possible distance from pumps, locking devices, elbows, expansion joints and other hydraulic
devices. It is especially not recommended to install sensors in front of the shut-off device if the
CAUTION
Until installation, keep the unit in the original container with all the
covers in position. The container and covers prevent contamination and
damage. When not in use, keep the connections covered.
WARNING
High pressures, temperatures and potentially poisonous pressure
media are dangerous, and can cause injury to personnel and damage to property
and the environment. Ensure correct installation, sealing of pressure interfaces
and connection of the equipment. Ensure correct operation of the equipment in
accordance with the specification. Use the applicable protection and obey all
safety precautions.
WARNING
For sensors intended for use in Explosive Atmospheres refer to
additional instructions on Hazardous Area Installation.
