*1) Measurement is possible if the fluid does not corrode the wetted parts and the viscosity is 3 mPa·s [3cP] or less. Please note that depending on the type of fluid, the internal packing may shrink or swell, causing water leakage.
*2) When 0.5 s is selected for the response time of the switch output, the repeatability is ±3% F.S.
*3) The operating pressure range and pressure resistance change depending on the fluid temperature. Please refer to the graph on p. 8.
*4) Clear when the power supply is turned off. It is possible to select the hold function.
      (Selectable at 2-minute intervals or 5-minute intervals)
      If you select the 5-minute interval, the lifespan of the storage element (electronic component) is limited to 1 million times (5 minutes × 1 million times = 5 million minutes = approx. 9.5 years when energized for 24 hours), so if you use the hold function, please use it within the lifespan after calculating the lifespan from the usage conditions.
*5) Response time when the set value is set to 90% for the step input.
      (In the case of temperature sensor output, it will be 7 s.)
*6) Response time until the value reaches 90% for the step input.
      (In the case of analog output of the temperature sensor, it will be 7 s.)
*7) 250 V AC with a temperature sensor.
*8) If the pipe diameter or pipe flow path is narrowed, the specifications may not be satisfied.
*9) Although the manufacturer is making efforts to improve the quality, products with slight scratches, stains, display color, uneven luminance, etc., on the external appearance that do not affect the performance are considered to be good products.
