Spanning
a temperature range of -200 to +400 deg .C., the Model T140
series incorporates a microprocessor which makes the use
of various features; including varied sensor and output modes,
while preserving compatibility with systems that use the
former Model 125 in data monitoring.
This single probe temperature alarm-monitor
spans a range that covers -200°C to +400°C (in various factory
set ranges), and is housed in a wall-mounted, or free-standing
box. The basic unit includes alarm on high and low temperatures,
with audible and visual alarm indicators (beeper and LED),
settable mute and alarm "chirp" periods, and a UL listed plug-in power supply. Custom programming & packaging can be provided to fit most temperature monitoring tasks.
The features of the model T140 that
make it suitable for applications such as built-in monitoring
of freezers, refrigerators, and walk-in environmental chambers
include; temporary muting of the alarm beeper for user-selectable
periods up to about 30 minutes (the beeper cannot be disabled
completely), optional relay contacts indicating a temperature
alarm condition or power failure, and for hookup to a remote
alarm device or telephone dialer.
In case of power failure, the unit
will go to battery mode for up to 100 hours, shutting down
all circuitry except a periodic "chirp" of the beeper and short flashes of the red "Alarm" LED to conserve power. Temperature readout is activated by pressing the "Delay" button, to read product temperature without opening the chamber.
The Model 140 alarms can easily be
connected to Hampshire Controls centralized monitoring systems,
using a single twisted pair common bus for both power and
digital data. Consult Hampshire Controls Corp. for available
options and configurations.
