ELECTRONIC LEVEL SENSOR 230V (1/2 NPT) (COML-230/012)

COML/H offers a simple and compact level monitoring system with an integrated alarm function. In case of an insufficient/overfilled liquid level in a receiver (oil or refrigerant) an alarm signal will be generated. This ensures the reliable operation of the refrigeration system and avoids greater damage to the system components.A Hall-effect sensor and a built-in float magnet system measuring the liquid level. Depending on the position of the float and the resulting change in magnetic field strength creates a variable output voltage.This is evaluated by an electronic board and the LED’s will be driven accordingly. As soon the liquid level reaches the yellow zone the output Signal S will be switched on with a delay of 10 sec. A further drop/rise of Level to the red alarm range causes the Relays switches with a delay time of 90 seconds into the alarm state. This signal can be used for data processing or shut down of the system. If a correct fluid level can be restored, the alarm and the signal (S) will be reset.To monitor the minimum level COML/H will be installed in the normal position.For monitoring the maximum level, the device is rotated by 180° for the installation (see Figure 1 on page 3). This means that one version can be used for both applications, minimum and maximum level control.
