PT1000 Electronic Digital Temperature Switch for air liquid
temperature measurement
The temperature switch STS is robustly designed and very easy to
use. The STS is suited for temperature monitoring, measurement and
control, such as used in cleaning liquid, hydraulic oil,
heat-carrying agent and lubricant etc. It is temperature switch,
transmitter and display in one and the same device. In its standard
configuration it has optional two switching outputs (PNP or NPN),
an analog output signal (0...20mA| 4…20 mA or 0...5V| 0…10 V) as
well as with RS485 Link.
STS temperature switch supports PT100 or PT1000, it is with high
measuring accuracy of 0.5℃. STS offers various functions including
switch delay, switch point settable, display environment
temperature, housing and display turnable and rotatable.
