Smart PT100 Temperature Switch with 4~20mA+2 PNP Output
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.
The temperature switch STS takes the high integrated ARM
industrial-grade MCU as the core. The STS ensures fast-speed and
precise temperature measurement and switch movement by carefully
adjustment and combining high-precision AD switch and high stabile
pressure sensor. The setup using the three big back-lighted buttons
and the display on machine make it very easy for on-site parameters
setting.
