High-precision temperature compensation
The temperature compensation element used is a platinum resistance thermometer (Pt 1000 Ω).Temperature compensation suited to a range of tasks You can select the appropriate temperature compensation for the temperature characteristics of the fluid you are measuring.
Self-diagnosis function for sensor faults
The sensor automatically determines whether it has deteriorated, and displays an error message.
Uses lead-free solder
To reduce the burden on the environment, lead-free solder has been used to mount the components on the printed circuit board.
