Operating conditions
3.7.1 Safety Precautions
To prevent possible injury when we receive the product, you must also tell us if the product has
been in contact with hazardous or toxic materials. Please supply the applicable Control of
Substances Hazardous to Health (COSHH) or Material Safety Data Sheet (MSDS) references
and precautions.
3.7.2 Important Notice
Service or calibration by unauthorized sources will affect the warranty and may not guarantee
further performance.
3.8 Electromagnetic Compatibility
The pressure sensor complies with the European Electromagnetic Compatibility Directive
2014/30/EU.
When appropriately installed the sensors meet and exceed the Commercial and Industrial
specifications indicated in Table
4:
3.8.1 Power Supply and Metering
The quality of the power supply and monitoring equipment will directly affect the EMC
performance of the entire system. Since “Druck Limited” has no control over the installation of the
sensor it must remain the responsibility of the user to ensure that the EMC performance of the
system is adequate.
To maintain good immunity from electromagnetic disturbances present on the system power
supply, the power supply should filter any transient interference from the incoming line and
present a clean regulated DC supply to the sensor. The monitoring equipment should likewise be
immune from the effects of electromagnetic disturbances and not impart disruptive signals on the
connections to the sensor.
The sensor is not intended for connection to a DC distribution network.
3.8.2 Cable Type
Due to the small size of the sensor it is unlikely to be directly affected by radiated RF energy. Any
RF energy that gets into the circuit will probably enter via the interconnecting cable.
To minimize the effect of nearby circuits and events, it is necessary to use screened cable
between the sensor and power supply / monitoring equipment. Failure to do so will invalidate the
EMC tests conducted by “Druck”.
The choice of cable type should reflect the environment through which it is going to run. Screened
cable should always be used where electrical noise is present. Good cabling practice will be
reflected in signal quality.
