Temperature Sensor
Specifications
Operating Pressure and Proof Pressure
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.
Note 1) Refer to “Measurable Range for Ethylene Glycol Aqueous Solution” on page 4. Measurement can be
performed with a fluid that does not corrode wetted parts and has viscosity of 3 mPa·s [3 cP] or less.
Note 2) Operating pressure range and proof pressure change according to the fluid temperature. Refer to the
graphs below.
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.)
Note 4) When the temperature sensor is used, it will be 250 VAC.
Note 5) Refer to “Wetted Parts Construction” on page 7 for details.

Measurable within this range
• The smaller the piping size, the more the product is
affected by the straight piping length.
• Fluid pressure has almost no affect.
•
Low flow rate lessens the effect of the straight piping length.
• Use a straight pipe that is 8 cm or longer in length to
satisfy the ±3% F.S. specification.
(11 cm or longer for 100 L/min type)
∗ No data for 4 cm, or for under 5 cm, as these
cannot be used due to piping dimensions.
