Calibration Part Numbers
|One person can calibrate your Delphian gas monitor
alone. Conventional gas monitors require two people with
walkie-talkies, one at the
adjust zero and span and one
at the sensor to apply calibration gas. With Delphian's One
Person Remote Calibration, zero and span adjustments are made at the
sensor by the same person applying calibration gas. This is
achieved by installing a Remote Calibration Module.
|This module eliminates the need for an alarm override
switch at the controller. When one person calibration takes
place, controller alarm circuits are automatically disabled.
False alarms are eliminated. Approximately 45 seconds after
calibration, alarm circuits are automatically re-engaged. Alarms
forgotten and left disabled in the override position are a thing of
The module fits over the
transmitter in the explosion proof housing. See the zero adjust,
span adjust, connection to transmitter and remote calibration meter
|The remote calibration module can be factory installed
or can be added to the standard Delphian system later. Retrofit
installation can be accomplished in the field in less than five
minutes. No changes are required at the controller and no wires
or jumpers need to be cut.
A Sensor Extension Kit
is available so that it is possible to calibrate a sensor installed in a
difficult to reach or hazardous location without needing to be there
yourself. The Sensor Extension Kit allows the separation of the sensor
from the transmitter up to a distance of 100 feet. The kit contains an
EXP junction box and all of the hardware and connectors (excluding the
extension wires) required to remotely locate the transmitter at a distance of
up to 100 feet from the sensor. The sensor is installed in the EXP junction
box and plugged into the connector provided inside. The EXP box and
sensor a re mounted where needed for monitoring. Extension wires are
connected to the barrier strip provided in the EXP junction box and routed to
the transmitter EXP junction box. There they are terminated with an
adaptor (supplied with the kit) that terminates with crimp connectors at one
end and a socket that plugs into the transmitter at the other. Also required
is a ported sensor (or ported adaptor for the sensor) and a remote calibration
module for the transmitter.
