Ultraviolet intensity sensor, Trojan reference 793200-004, supplied with cable. The number is the manufacturer's own part number and is the safest string to match when identifying a replacement, because Trojan sensors that look identical differ in output scaling and calibration. This is the long-cable version of the sensor: 793200-004 carries a 21 ft lead, while 793200-001 is the same sensor with a 3 ft lead and is listed separately as item 1536-1206. Cable length is the only difference between the two, so choose on the run from the reactor to the controller and not on the sensor itself. Reference number 793200-004. Supplied by cBallast on quote-to-invoice terms; lead time and freight are quoted per RFQ against the destination Incoterm.
