EIT Compact Sensor

The Compact Sensor from EIT is a breakthrough in UV sensor technology. It is extremely resistant to UV solarization in even the most intense UV fields. Solarization – the degradation of optical components caused by intense UV light – is virtually eliminated in the new design.

Innovative design and improved materials in the sensor make it possible to monitor an intense UV source for thousands of hours without perceptible solarization.

The Compact Sensors is very small in size; ruggedness and hermetic sealing make it ideal for use in many industrial applications.

The Compact Sensor generates a signal proportional to the intensity of UV light impinged  on the face of the sensor. This signal is fed via a 3m shielded cable to one of four display options – EIT’s Multibrite, Online UV Intensity Display Module, DIN Rail Mount UV Intensity Monitor, or Battery-Powered Display Module. When the UV lamps and reflectors are new, the display is set to show a 100% relative intensity. A decrease in the displayed percentage shows the gradual degradation in the UV lamp’s output compared to its output when new. The relative intensity values can be converted to absolute values in watts per square centimeter by comparing the percentage to an intensity reading from an EIT radiometer.

The sensor offers great flexibility in installation. Since solarization is no longer a major concern, the sensor can be mounted to directly view any section of the lamp. Many applications allow installation where the sensor can monitor the UV light directly from the lamp or from its reflector. In space-limited applications, the sensor can even be mounted behind the reflector. The sensor package is sealed to protect its optics from humidity and harmful vapors. The Compact Sensor is available in two standard housing sizes described below. Each sensor is available in EIT’s UVA, UVB, UVC or UVV bandwidths.

Compact Sensor-Dash 1 Assembly (CS-1)
The Compact Sensor (CS-1) comes with an optional air/nitrogen purge, which allows operation in less than ideal environments. Slight positive pressure (few PSI) of air or nitrogen flowing through the purge assembly will keep the sensor window clean in dirty or hostile environments. A screw is provided in the kit if the user elects to not use the purge. The approximate acceptance angle of the CS-1 UVA sensor is 5o degrees.

Compact Sensor-Dash 2 Assembly (CS-2)
The CS-2 housing is a height-reduced version of the CS-1 sensor. The purge assembly that is present in the CS-1 sensor has been removed making the CS-2 version of the sensor truly compact. The approximate acceptance angle of the CS-2 UVA sensor is 130 degrees.

To obtain consistently good curing results, it is important to know when to perform UV system maintenance. The Online UV Intensity Display Module, when used in conjunction with EIT® Compact Sensors, forms an electro-optic system designed to track a single UV lamp. To get good curing results consistently, it is important to know when to perform UV system maintenance.
