Different interfaces of BTL
Micropulse transducers are available with a variety of different interfaces and can thus be
easily connected to controllers or simple display or processor units.
Generally differentiates between the analogue and the digital interface.
- Voltage output
The output voltage is directly proportional to the position of the position transducer on
the measuring section. - Current output
The output current is directly proportional to the position of the position transducer on
the measuring section. - Pulse interface
The time between a polling and the response pulse is directly proportional to the position
of the position transducer on the measurement path. The transmission of the impulses
with RS485 / 422 differential drivers guarantees interference-free transmission up to 500
m cable length. - Synchronous serial interface SSI
The position of the position transducer on the measuring path is transmitted serially to
the controller in a data word. Micropulse position transducers with SSI interface can be
connected directly to controllers or axis control cards with an SSI interface. - Digital I/O interface
The displacement sensors can be directly connected to the controller via digital inputs /
outputs and is therefore a cost-effective solution compared to analogue coupling. - Quadrature interface
The encoder with quadrature interface is connected directly to a standard rotary encoder
interface (90 ° phase shift, A & B)
BTL distance sensors are also available with network interfaces.
