这种智能微型传送器/开关具有一个特大号显示器，

for an ambient temperature of max. 40°C) Typical accuracy Transmitter 2-wire version for 0°C < T < 70°C 

Complete device data (pipe + electronic module) Pipe diameter Any pipe with sensor connection 1/2” 

Measuring range up to 1, 2, 5, 10, 20 or 50 bar Medium temperature -20 up to 100°C (+100°C 

The switching points can be programmed with the three-key keypad under the display. 

In addition, the process value can be transmitted to the PLC (4-20 mA).

• Indication, monitoring, transmitting and continuous or On/Off control in one device

for -20°C < T < 0°C for 70°C < T < 100°C Switch version  ±1% of F.S.* ±1% ± 0.03% of F.S.* / °C 

• Transistor or relay outputs for On/Off control or alarm function

This intelligent mini transmitter/switch with an extra-large display is specially designed to switch alarms

 and to establish a monitoring system or an On/Off control loop.

特别适合监控极限值或者 On/Off 或持续型调节电路。

The connection to the process in the piping is made using standard fittings (G1/2, NPT1/2, Rc1/2).

 • Output signal 4...20 mA, 2-wire for continuous control
