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. Refer to the list of applicable fluids on page 24.
Note 2) When 0.5 s is selected for the response time of the switch output, the repeatability becomes ±3% F.S.
Note 3) Operating pressure range and proof pressure change according to the fluid temperature. Refer to page 13.
Note 4) 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 5) The response time when the set value is 90% in relation to the step input.
Note 6) The response time until the set value reaches 90% in relation to the step input.
Note 7) Refer to “Wetted Parts Construction” on page 14 for details.
