TWISTIK |
|
| All the same great features as the Sensor
Stik but the TWISTIK provides some additional maintenance-saving
features. The instrument can be calibrated either in place or off-site.
A built-in lithium battery keeps the transmitter continuously under
power while an innovative twist-lock connector enables users to quickly
remove the transmitter for off-site maintenance. This battery also
enables the TWISTIK to be installed without the typical warm-up time.
Built-in recharging circuitry quickly restores the battery to its
standard two-week lifetime.

Sentinel® Infrared Combustible Gas Detection Transmitter
Detection of Combustible Gas Using Infrared (IR) Sensor Technology.
This IR Combustible Gas Transmitter provides a very stable and low maintenance measurement
of the Lower Flammability Limit (LFL); and is a lower "cost of ownership"
alternative to conventional catalytic design gas detectors. A folded path, dual detector
scheme in standard size packaging offers replacement for conventional catalytic design gas
detection transmitters.
It is ideal in tough applications where poisons, frequent releases, or limited access make catalytic technology difficult to maintain.
Features:
- Cannot be "poisoned"
- Doesn't require Oxygen
- Once a year calibration
- Switch selectable linearizations
- Over five year detector operating life
- Five year detector life
- Nonintrusive calibration via magnetic wand
Condensed Specifications

6200
Single Channel Receiver
|
|
| The Series 6200 single channel receiver
provides a three-digit LED display of gas concentration, plus LED low
alarm, high alarm, and fail indicators. Front-panel pushbuttons enable
users to set alarm levels and reset alarms. An internal switch allows
alarm outputs to be inhibited for periodic system calibration and
adjustment.
Receivers are available in both panel-mount and wall-mount configurations. The 24VDC-powered panel-mount configuration is housed in a compact NEMA 1 enclosure, and provides common low alarm, high alarm, horn, and fail open collector outputs. Housed in a NEMA 4x enclosure, the wall-mount configuration provides a 110VAC (optional 220VAC) power supply and relays for these open collector outputs. A front-panel pushbutton on both versions enables users to reset alarms. The single channel receiver also provides 0-1VDC or 0-10VDC analog concentration output. Features:
