Screw-in Resistance Temperature Sensor Page-4
3 Safety Instructions
Select the correct resistance thermometer based on measurement range, design, suitable material in
contact with medium (corrosion) and specific measurement conditions before mounting, start-up and
operation.
Further important safety instructions are in the individual chapters.

3.2 Personnel Qualification
3.3 Special Hazards
For mounting and start-up of the temperature sensor, the personnel will have to be familiar with the applicable
country-specific regulations and directives and have the required qualifications. They must have knowledge of
measurement and control technology, be familiar with electrical circuits, be able to carry out the work described
and recognize potential hazards independently. Depending on the operating conditions, other knowledge may
also be required, e.g. of corrosive media.
Risk of injury if qualification is insufficient
Improper handling can lead to considerable property damage and injury.
- The required tasks as described in this operating manual should only be conducted by qualified
personnel with the qualifications described below.
- Keep unqualified personnel away from hazardous areas.
3.1 Intended Use
The resistance thermometer METS-WTEx is suitable for temperature measurement in liquid and gaseous media. It
has a maximal range of -50…+425°C and can be used under a pressure of up to 25 bar.
The sensor is designed solely for the use and intended purpose as described in this operating manual.
The technical specifications as described in this operating manual are mandatory. Inappropriate handling or operating
the device outside of its technical specifications requires an immediate shutdown and inspection by the manufacturer.
When the device is transported from a cold into a warm environment, condensation can cause a device malfunction.
Wait for device temperature and room temperature to equalize before a new start-up attempt.
The manufacturer shall not be liable for claims of any kind based on operation contrary to the intended use.
Select the appropriate temperature sensor with regard to version and application requirements before
mounting or start-up. Comply with the relevant national regulations (e. g. standards) and comply with
the applicable standards and directives for special applications (e. g. with dangerous media such as
acetylene, flammable gases or liquids and toxic gases or liquids, or with refrigerating systems and
compressors). Non-compliance with the relevant regulations can cause serious injuries and
property damage!
Electrostatic discharge (ESD) protection is required.
The proper use of grounded worktops and personal wristbands is required when working with open
circuits (PCBs) to prevent damage to sensitive electronic components caused by electrostatic
discharge.
Rest media in dismounted devices can represent a danger to people, the environment and the facility.
Please take sufficient security measures!
Do not use this device in safety or emergency stop installations. Improper use of the device may result in
injury.
In case of fault, corrosive media with extreme temperatures and under high pressure or vacuum can be in
contact with the device.
Danger to life due to electric current. If live parts are touched, there is an immediate danger of death.
Installation and mounting of electrical equipment may only be carried out by qualified electricians.
Operation with a defective power supply unit (e.g. short-circuit from mains voltage to output voltage)
can cause life-threatening voltages on the unit.
