DESCRIPTION

REMARKS: Sensor LB-781 is curently unavailable.

Integrated road sensor LB-781 is is designed for surface and road interior temperature measurement as well as road surface conductance (reverse of resistance). It is a stationary device, of small size powered from an outside power supply. It is characterized by a modern construction based on efficient and energy saving microprocessor controller.

For measurement the device uses data from two temperature sensors Pt-1000 and a comb-shaped conduction sensor. Basing on the knowledge of nonlinear sensor characteristics and digital calibration data stored during the calibration process in a device's memory - the microprocessor (built-in the device) counts the actual measurement results. Those results are sent (in a digital form) from the device to a supervisory system of data collection (i.e a panel LB-741, a LAB-EL meteorological station LB-770, a converter LB-486 or a PC computer).

The device is equipped with a digital interface S300 LAB-EL.
