Diverse lineup of sensors available
Two types of sensors are available: a lead type which can be directly thrown into the tank or placed in the tank with an immersion holder, and a connector type for direct insertion into piping or with a flow-through holder. Materials that can accommodate special water applications are also offered.

Possible to be used in a panel-mounted configuration
This transmitter is easy to install while providing standard functions.
