Technical data: STG-B & STG-F-LEAKDETECTOR

The STG sensor has the function of detecting any leakage or opening of the safety valves in industrial refrigeration systems, operating with any type of refrigerant gas.

When the warning or alarm value of the presence of refrigerant gas is exceeded (Threshold values set by the user), the device will signal the alarm to the controller and activate a visual signal locally. Furthermore, through the MODBUS protocol it is possible to view values such as% Gas Presence,% Alert Gas Presence and Alarm Gas Presence% and set the relative thresholds.

Available in 2 different versions:

  1. STG-B-LEAKDETECTOR: Equipped with a relay with three contacts (C-NO), a Modbus RS-485 protocol and powered by 24 V DC.
  2. STG-F-LEAKDETECTOR: Equipped with a relay with three contacts (C-NO), a Modbus RS-485 protocol, two analogue outputs 0-10V and 4-20 mA and powered in 24 V DC.

In addition, both versions will be equipped with a local visual alarm signal that also allows the display of the status in real time.
By means of the 1 ”threaded connection with which it is equipped, the STG sensor can be easily installed on a pipe leaving one or more safety valves present in the system. It can be used in stand-alone applications or connected through the analogue, digital outputs, or through the RS485 Modbus serial link, to a control system (electronic controllers, PLC or third-party devices) capable of carrying out any alarm procedures.

Delivered without a cable but with a plug. Find the specifications for the plug under the tab Specifications.
