Specifications

Note 1) Cleared by turning off the power supply. It is possible to select the function to memorise it. (Every 2 or 5 minutes) When 5 minutes memorising is selected, the

lifetime of the memory element (electronic part) is 1 million times (5 minutes x 1 million times = 5 million minutes = Approx. 9.5 years for 24 hour energizing).

Calculate the lifetime based on your operating conditions before using the memorising function, and do not exceed it.

Note 2) The response time when the set value is 90% in relation to the step input. (The response time is 7 s when it is output by the temperature sensor.)

Note 3)

The response time until the set value reaches 90% in relation to the step input. (The response time is 7 s when it is analogue output by the temperature sensor.)

Temperature Sensor Specifications

Note 1) The rated temperature range is for the temperature sensor alone.

The fluid temperature range specification of the flow switch as a whole

is 0 to 90°C.

Note 2) The response time is for the temperature sensor alone.

The OUT2 can be selected from the output for temperature or flow

rate by button operation.
