|Delphian's Stand Alone Sensors
can be used with virtually any
controller, datalogger or
management systems that
accepts a 4-20 mA input.
Delphian's Stand Alone Sensors
are available for every
sold by Delphian.
Field Installation Tough
The Stand Alone Sensor includes Delphian's patented
Transmitter (which is epoxy coated for complete environmental protection). This puts
sensor power regulation and support electronics where it counts - at the sensor location.
Otherwise, sensor performance can be degraded by changes in electrical resistance caused
by moisture, corroded terminals, splices or loose contacts in the wires between the sensor
and controller. Delphian's Stand Alone Sensor ensures that power to and the signal from
the sensor are not degraded and therefore guarantees maximum sensor performance and
reliable sensor signals.
Only Three Wires Needed
Only THREE wires are needed between the user's power supply and controller and the
Delphian Stand Alone Sensor. Shielding is normally not required since RFI and surge
protection circuitry are built into the Stand Alone Sensor.
One Person Calibration at the Sensor
The Delphian Stand Alone Sensor is calibrated by one person at the sensor location.
Nothing is done at the controller. When the Delphian remote calibration meter is plugged
into the Stand Alone Sensor the signal is disrupted so that user alarm circuits are
automatically disabled for that sensor only. Other detection points remain in service.
Long Sensor Life
The longer a sensor lasts, the lower are the maintenance costs. A sensor's life is
governed by its operating temperature. Operation above or below a sensor's optimum
operating temperature shortens its life. Delphian's unique Sensor Saver Transmitter
guarantees constant temperature sensor operation, assuring long and stable sensor life
even in continuous high ambient temperatures or gas concentrations. Sensor burn-out is
eliminated, zero and span drift are negligible. Sensor Saver delivers maintenance and
calibration cost savings.
