Thanks to the firm’s long experience, E.D. Elettronica Dedicata has design the 3th generation of Rotating Temperature Transmitter (RTT) to maximize the measurement stability and accuracy over a wide operating temperature range in a contactless way.
With this new design it’s possible to obtain in a short time a wide range of customizations for sensors and outputs, and mechanical assembling. This new system is also very reliable against incorrect mechanical installations and unstable and variable power.
The hollowed mechanical parts, rotating and stationary, permits to connect this model of transmitter with different orientations even when the space available is very tight.
Self calibration: it doesn’t need a calibration on the field even for the spare parts.
Several self tests are performed to assure the measure accuracy.
Rotating and stationary parts can be swapped or replaced individually.
Fast troubleshooting through a simple coding for each output, without disassembling the parts:
Sensor short circuit
Sensor open/ broken
No communication between parts
Measure not reliable
MODBUS with RS485, isolated (Optional).
PT100 output (Optional) for direct replacement of the mechanical slip ring.
Output completely isolated from power supply for better noise immunity.
DIGITAL ROTATING TRANSMITTER, that transmits contactless general I/O; Inputs or Outputs as general I/O with “ready” contact.
All built-in, it doesn’t need external signal condition board.
Standard range 0-300 °C. (Configurable to order between -200°C to 1500°C).
