Important
Be sure to read and understand the entire
instruction manual before installing or operating
the gas detection system. This product can be
used with a variety of Det-Tronics gas detectors to
provide early warning of the presence of a toxic or
explosive gas mixture. Proper device installation,
operation, and maintenance is required to ensure
safe and effective operation. If this equipment
is used in a manner not specified in this manual,
safety protection may be impaired.
ApplicAtion
The FlexVu
®
Model UD10 is recommended for
applications that require a gas detector with digital
readout of detected gas levels as well as analog 4-20
mA output, relay contacts, and/or Modbus RS485. The
UD10 Universal Display Unit is designed for use with
Det-Tronics gas detectors listed in Table 1. The display
unit is designed and approved as a 'stand alone' device
and performs all the functions of a gas controller.
Gas concentration and unit of measurement are
displayed on an alphanumeric display. The display
unit provides a linear isolated/non-isolated 4-20 mA
DC output signal (with HART) that corresponds to the
detected gas concentration.
All electronics are enclosed in an explosion-proof
aluminum or stainless steel housing. The display unit is
used with a single detector that may be either coupled
directly to the UD10, or remotely located using a sensor
termination box.
The UD10 features non-intrusive calibration. A magnet
is used to perform calibration as well as to navigate the
UD10's internal menu.
