Hydac CS1000 series User Manual

Reading the analog output
Fluid temperature TEMP
The current range 4.8-19.2 mA or voltage range 2.4-9.6 V is, depending on
the fluid temperature of -25°C-100°C (resolution: 1°C) or -13°F-212°F
(resolution: 1°F), as shown in the table below.

The current I or voltage U can be calculated for a given temperature as
follows:
I = 4.8 mA + (temperature [°C] + 25) x (19.2 mA - 4.8 mA) / 125
I = 4.8 mA + (temperature [°F] +13) x (19.2 mA - 4.8 mA) / 225
U = 2.4 V + (temperature [°C] + 25) x (9.6 V - 2.4 V) / 125
U = 2.4 V + (temperature [°F] + 13) x (9.6 V-2.4 V) / 225
The temperature in °C or °F can be calculated for a given current I or
voltage U as follows:
Temperature [°C]= ((I - 4.8 mA) x (125 / 14.4 mA)) - 25
Temperature [°F]= ((I - 4.8 mA) x (225 / 14.4 mA)) - 13
Temperature [°F]= ((U - 2.4 V) x (125 / 7.2 V)) - 25
Temperature [°F]= ((U - 2.4 V) x (225 / 7.2 V)) - 13
