*1 This is the value when considering linearity + hysteresis + repeatability in a stable environment of 23°C 73.4°F.
*2 The repeatability, based on consistent conditions, is the difference in the detection points at the time of fluctuations in the repetition.
*3 When the temperature of the piping exceeds 80°C 176°F, do not connect the cable.
*4 Condensation may cause measurement failure or breakage. To prevent condensation, take the following measures:
• Make sure the ambient temperature is the same or lower than the fluid temperature.
• Use A/C for dehumidification.
• Keep the sensor 30 cm 11.81" or more from the cooling pipe using connective piping.
*5 Consumption current including output is 0.3 A and under.
*6 This is the value when the measured fluid is water and a KEYENCE adapter is used.
*7 IO-Link specification v1.1/COM2 (38.4 kbps) is supported.
*8 See "7" in "Other precautions" on P.13 for measures on preventing condensation.
*9 Only GP-M001T/M010T/M025T
