AMES Environmental Measurement Systems
HSS VPF-710 Visibility Sensor
Is suitable for use in any system where a digital output to a computer or logger is required.
Features
Measures visibility and fog density.
Proven accuracy, reliability and repeatability.
Minimal maintenance requirements and running costs.
Data Output
Visibility Sensor is configured with RS-232C signal output as standard with RS-422 communications available as an option. The data is output in various ASCII data strings, such as a small compressed data string.
Construction
Visibility Sensor is a single lightweight unit and can easily be installed by one person.The sensor is constructed of dip brazed high grade aluminium.
Maintenance and calibration
The Visibility Sensor is fully calibrated at the time of manufacture. Routine maintenance, including a check on calibrations, can be performed easily by one person in a matter of a few minutes and a re-calibration takes only slightly longer.
Operation in temperature extremes
The Visibility Sensor operates in temperatures ranging from -50º C to +60º C. For operation below -32º C the heated version is recommended.
Visibility senzor system
The Visibility Sensor is also supplied with a stainless steel mounting kit.
