General Purpose Immersion Temperature Sensor

Locking Screw Cover, Multiple Conduit Holes

The Series I2-2 General Purpose Immersion Temperature Sensor is ideal for
monitoring hot and chilled water lines throughout a building or mechanical room. The
plastic housing is in the shape of a standard junction box with multiple knockouts for easy
conduit access. The locking cover prevents unauthorized occupants from tampering with
the temperature sensor. The Sensor I2-2 can be ordered with a choice of 11 output options
that allow it to communicate to any standard building control system.

Note: A Series IW2 Thermowell must be used on pressurized air and water lines to
prevent leakage around the probe.
