TMS-BASIC
The TMS-BASIC measures the speed of moving vehicles and transmits it via an RS-232 link to a display or control centre.
Equipped with an on/off relay with an adjustable trip threshold, it can both transmit the speed and activate a specific device in the event of overspeed.
This Doppler radar is non-intrusive: it can be installed above ground in a few minutes, without any civil engineering work.
Operation and strengths
- Insensitive to light, colour, humidity or dust
- RS-232 output + relay
- Reaction time less than 50 ms
- No maintenance required
- Range from 120 to 150 m
- Aluminium housing and IP65 rear connector
- Lightweight, easy to install
- Easy assembly: M8 nuts and bolts included
Adjustable parameters:
- direction of direction (incoming, outgoing or bidirectional)
- unit of measurement: mph or km/h
- minimum and maximum speed for detection: the radar only transmits the values within these limits
- minimum and maximum speed threshold for tripping the relay: if the measured speed is within these limits, a contact is given
- relay holding time
- delay between measurements
