Specifications (Remote Sensor Unit)
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) 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.
Note 4) Refer to “Wetted Parts Construction” on page 14 for details.
