Hauser 9
NOTICE
Danger of breakage of the sensor due to corrosive or abrasive fluids!
‣
Verify the compatibility of the process fluid with the sensor material.
‣
Ensure the resistance of all fluid-wetted materials in the process.
‣
Observe the specified maximum process pressure.
Verification for borderline cases:
‣
For special fluids and fluids for cleaning, Hauser is glad to provide assistance
in verifying the corrosion resistance of fluid-wetted materials, but does not accept any
warranty or liability.
Residual risks
The external surface temperature of the housing can increase by max. 15 K due to the
power consumption of the electronic components. Hot process fluids passing through the
measuring device will further increase the surface temperature of the housing. The surface
of the sensor, in particular, can reach temperatures which are close to the fluid
temperature.
Possible burn hazard due to fluid temperatures!
‣
For elevated fluid temperature, ensure protection against contact to prevent burns.
