Current Sensors And Switches
Honeywell current switches can detect whether
current is flowing and then transmit the status
to a building management system, DDC or
PLC controller. Honeywell current transmitters
measure the level of operating current and can
be used to monitor equipment or drive other equipment with a
modulating output. Both current switches and transmitters can
be used to detect a motor failure, belt loss or slippage, or a
mechanical failure to help prevent further damage and reduce
downtime. Because Honeywell current sensors are rated at up to
250 amps, you can meet high-amp applications without the need
for a transformer. And Honeywell offers current switches with a
very low trip point of 0.20 amps.
Enthalpy Sensors
Honeywell enthalpy sensors are used with
Honeywell economizer logic modules to
permit the use of outdoor air as the first stage
of cooling in HVAC systems. The long-lasting
solid-state sensing elements are accurate and stable
over time. Maximum economizer savings are achieved when two
enthalpy sensors are connected to one economizer logic module
for differential enthalpy changeover control.
Differential Pressure Sensors
All Honeywell differential pressure sensors offer
field selectable 4-20 mA, 0-5 Vdc and 0-10 Vdc
outputs, uni- and bi-directional outputs, push
button and digital inputs to zero the output, and
configurable pressure ranges. Use P7640 dry
media sensors in applications where you want measure extremely
low pressure, such as clean rooms, hospitals, fume hoods and
computer rooms. Use the PWT Series to monitor and control
pump differential pressure, chiller/boiler differential pressure drop
and CW/HW system differential pressure.
Specify Honeywell Sensors And Save
Honeywell sensors have always been competitively priced, and
today Honeywell sensors continue to be one of the industry’s best
values. Add in the fact that their ease-of-installation increases your
productivity and you’ll see that Honeywell sensors are the smart,
cost-effective choice.
SENSORS FOR ANY APPLICATION
2
Honeywell’s complete line of sensor's cover all necessary control
applications and mounting options, making Honeywell your best
sensor source.
Temperature Sensors
No matter what control application or
mounting option you can imagine,
Honeywell offers a temperature sensor
that fits your needs — including wireless
TR20 sensors for easy installation and easy
sensor relocation. From averaging, immersion and outdoor
sensors to duct mount, wall mount and strap-on sensors,
Honeywell sensors cover every application and installation.
Humidity Sensors
Highly accurate, stable humidity
transducers designed for use with
HVAC controllers, thermostats and direct
digital controllers, Honeywell humidity
sensors feature a ceramic technology that’s affected by
condensation. Applications include room comfort, rooftop
units, air handlers, air conditioning and anywhere relative
humidity is tightly controlled.
Dew Point Sensors
Suitable for mounting on flat and round
surfaces, the Honeywell dew point sensor
is used to regulate cooling performance,
switch cooling systems ON and OFF, and
signal if the temperature is approaching the
dew point.
CO
2
Sensors
The Honeywell CO2 sensor includes
state-of-the-art non-dispersive infrared
(NDIR) technology plus a corrosion-free-
designed sensing chamber that provides accurate
and stable CO2 readings for years, avoiding costly
and inconvenient re-calibration. A patented gold-
plated sensing chamber eliminates a primary source
of dirt. Paired with a Honeywell economizer, the Honeywell
CO2 sensor can triple year-round savings over “cooling only”
economizing. The sensor is used in demand control ventilation
applications to maintain acceptable levels of CO2 in the space.
