The Model U9500 Infiniti™ Transmitter is designed to be used Features
with Det-Tronics gas detectors for continuous monitoring of • User-friendly setup
dangerous gases.
• Non-intrusive calibration using the internal magnetic reed
Gas concentrations are displayed on an alphanumeric display in switch, or an externally located pushbutton (not included)
%LFL, ppm, or %Vol, depending on the sensor. The transmitter • Automatic fault diagnostics and annunciation
provides a 4 to 20 milliampere output signal that corresponds
to the detected gas concentration. An optional relay package is • Sensor sensitivity and end of sensor life indication
available. • Optional relay package provides three alarm relays (high, low,
and auxiliary) and one fault relay.
Each Infiniti transmitter is used with one sensor. The sensor may
be mounted directly to the explosion-proof Infiniti housing, or it Application Flexibility
may be located remotely using a sensor separation kit. • Compatible with a wide range of Det-Tronics sensors
Typical applications include: • Field adjustable programming options include:
Operating range (toxic sensors only)
— Confined spaces where gas/vapor leaks can concentrate to Alarm setpoints
explosive or toxic levels or where oxygen levels need to be Calibration gas concentration
monitored (enclosed processing areas). Relay operation latching or non-latching, energized or
— Known high risk leak locations (points within processing de‑energized coils (relay package optional)
areas, compressor buildings). Automatic or manual calibration
— General open area coverage (storage areas). Current loop adjustment.
