Node Internal Contact Temperature Sensor; Node Internal Tev Sensor - EA Technology UltraTEV Monitor Operating Manual

EA Technology

2 x Ultrasonic Sensor: These inputs are for the connection of external ultrasonic probes.
The Monitor supports the connection of both air and contact probes.

Cable PD Sensor: This input is for the connection of an external RFCT for the detection of
Cable PD.

Node Communication: This socket is for connecting to a Node further downstream along
the daisy chain. Always connect from the Node socket to the Server connection of the next
Node.
 Server Communication: This socket is for connection to upstream (towards the Hub Unit)
Nodes along the daisy chain or to the Hub Unit itself.
The two communication ports on the Node make use of Ethernet style sockets but
these are NOT Ethernet and should not be connected to Ethernet systems.

4.1.3 Node Internal Contact Temperature Sensor

The Monitor includes a contact temperature sensor which measures the surface temperature of
whatever surface the Node is mounted on. The temperature sensor is visible as the aluminium disk
on the rear face of the Monitor Node. The temperature is logged every 3 seconds and the average
value recorded at the Hub Unit.

4.1.4 Node Internal TEV Sensor

The internal TEV sensor is located in the top right corner on the face that touches the switchgear.
This sensor is always considered to be active and therefore its corresponding data is always logged.
