Triboelectric probe interfacing
The E9T control unit can interfaces an analog or digital triboelectric probe. The probe is a microprocessor-based
measuring instrument designed to detect and measure dust emissions caused by breaking of bag filters.
The analog triboelectric probe is provided of industrial 4-20mA current-loop isolated output to long distance
transmit the emission value read to an E9T control unit. The current-loop line is more suitable in plant where
there are high peaks noises and electromagnetic disturbances.
The digital triboelectric probe is provided of industrial RS-485 isolated communication port to transmit emission
value read and receive some configuration messages. The communication protocol is proprietary and can only
work with E9T control unit and Eco-Net family devices of Turbo. The digital line is more suitable when fast
response is needed.
The standard Turbo triboelectric probe is provided of both analog and digital interface. Due to different electrical
reference levels of analog and digital outputs, the end-user must connect only in one way, avoiding to connect
both analog and digital at the same time.
Analog probe
The E9T control unit interfacing to analog output of the probe is shown in below schematics.
