The analog output provides an industry standard signal for input to Data Acquisition Systems, Integrated Control Systems and Distributed Control Systems.

To obtain consistently good curing results, it is important to know when to perform UV system maintenance. Maintaining the cleanliness of the reflector is important in order to operate your UV system effectively and efficiently. If the lamps are only replaced at set time intervals, they may be replaced too soon or too late. This creates needless waste of both money and product. The human eye, unable to detect degradation in UV output, must rely on an instrument designed to monitor only UV within a specified bandwidth. The Online UV Intensity Display module will continuously monitor the output of a single lamp.

The signal from the EIT Compact Sensor is converted to a voltage level that is supplied to the display. The continuous 2 1/2 digit display represents the percentage of lamp output relative to the initial calibration level.

In addition, the user settable low level threshold will be monitored and a red low limit indicator light will warn the user that this threshold has been breached. Otherwise, the green above threshold light will be visible. A normally open or normally closed relay is also provided.

Powered by 24 volts AC or DC, the unit may be mounted inside the control panel of the UV system so that its display is easily visible to the user. If space does not exist within the control panel of the UV system, it may be mounted near the control panel.

The unit includes a 0-10 volt buffered output proportional to UV intensity. This output easily interfaces the Online UV Intensity Display Module to a Programmable Logic Controller, strip chart recorder, personal computer or other data collection device capable of accepting a 0 to 10 volt analog input signal.

Online UV Intensity Display Modules are easy to install using a supplied drill template. The sensors are mounted permanently viewing a UV source and are normally equipped with 10’ (3 meters) cable. Several hardware items are supplied to simplify satisfactory sensor mounting. The sensors work with arc (electrode) and microwave (electrodeless) systems equipped with a variety of lamps – mercury vapor and mercury additive lamps. Sensors are ordered in 250-260nm, 280-320nm, 320-390nm, or 395-445nm spectral ranges. Extender cables in 10’ lengths are available.
