Product Specification

1. Application

2. Description

The main measuring module is located in a robust metal housing. The measuring chamber consists of anodized aluminum. Through the perforation in the measuring chamber the internal sensors can be filled with insulating oil. The BDVB sensor is equipped with a Parker RI1EDX3 / 471 connector which allows the device to be screwed on at the target location. The sensor can be mounted in any orientation, but a free oil flow through the measuring chamber must be guaranteed. The connection for the cable is located at the top of the sensor. The connection between the TrafoStick and the control unit is established with the WEiPU ST1210 / S9 connection using the cable supplied. The sensor is connected to a computer, router, modem orsimilar device using the TCP-IP cable supplied.
