*1 This is the value when considering linearity + hysterisis + repeatability in a stable environment of 23°C.
*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, do not connect the cable.
*4 Consumption current including output is 0.6 A and under.
*5 The maximum load resistance R will be the values below in response to the electric voltage E. When 10-23V: R = {38 x (E-10) + 128} Ω When 23-30V: R = 622 Ω
