Features
Transmitters with remote device are suitable for the following operation conditions:
v Mediums with high temperature should be isolated with transmitter.
v Measured mediums have corrosion to sensitive scripts of transmitters.
v Suspending liquid or mediums with high viscosity
v Measured mediums solidize or crystalize due to change of environment or technological process temperature.
v Strict purification of measuring head is needed for replacing measured mediums
v Measuring head must be kept clean and sanitary.
v Seal pressure container measurement.
