tu1000 (the ultimate) transmitter
tu1000 series is the latest avatar of intelligent transmitters, ‘the ultimate’ gas sensor + transmitter with unmatchable features. It can detect either flammable or toxic vapours, oxygen enrichment or depletion or co2. It can provide 4-20 ma analog output and/or digital rs485 output. It can be interfaced with any standard process indicator or plc/dcs. It can be calibrated through non-intrusive magnetic device or through pc or through a hand-held unit (display version). It can provide three settable alarms, three relays, open collector outputs, and back-lit display – virtually anything you can ask from a transmitter.
tu1000d unit has a large transparent front window with a 4-digit back-lit display and 5-mode status leds providing 24/7 gas concentration reading and channel status.
tu1000 has a three-preset, software programmed, alarm thresholds corresponding to three leds indications. Further two leds provide visual indication of fault and power on. The tu1000 unit comes complete with a 1-relay output interface with an optional 3-relay or 2-open collector outputs, thus making it an ideal choice for large scale installations with varied applications.
