A SENSOR FOR CONDENSATION / CONDENSATE CONTROL SYSTEMS.  USED TO PREVENT: CHILLED BEAM CONDENSATION OR CHILLED BEAM CONDENSATE FORMATION,  OR CHILLED CEILING CONDENSATION & RADIANT PANEL CONDENSATION & "RAIN",  OR TO CONTROL CONDENSATE FORMATION ON LIQUID COOLED OR WATER COOLED HEAT EXCHANGERS  -    A CONDENSATION SENSOR OR  CONDENSATE SENSOR.

GET THE MAXIMUM COOLING EFFECTIVENESS FROM YOUR CHILLED WATER COOLING SYSTEM AND POSITIVELY AVOID CONDENSATION "RAIN" WITH A  CONSENSOR  BASED CONDENSATION CONTROL SENSOR.
~ RAPIDLY BECOMING THE INDUSTRY STANDARD ~
The CONSENSOR is a patented unique, and well proven condensation sensor that instantly reacts to the actual initial onset of the condensation process.  This response occurs before there is any perceptible trace of condensate ... well before there is any risk of "rain" or drip.    Virtually all other so-called "condensation sensors" are actually humidistats typically set to 80% to 90% RH (Relative Humidity).  When the adjacent  RH reaches the preset level, they signal a condensation condition well before it actually occurs.  Actually, condensation might never occur.   As a result, coolant flow is often stopped needlessly- often when it's needed most.  The more elaborate dew point based condensation sensors are similarly predicated on the immediate RH and share these same issues.

The CONSENSOR is based on an entirely different principle.  It includes an extremely responsive condensate sensing area that is intimately coupled thermally to your surface of interest - a pipe for example.  Both share the same atmosphere.  Consequently, when the pipe "sweats", that sensing area simultaneously "sweats".  The CONSENSOR's integrated microprocessor is programmed to initiate a condensation signal when a microscopic deposit of condensate appears on that sensing area ... as demonstrated in the YOUTUBE video. 

With a CONSENSOR based condensation control system, the coolant flow can safely continue at maximum capacity right to the brink of the condensation occurrence without risk of condensation "rain" or drip. This has been proven in hundreds of chilled beam HVAC installations, in water cooled power supplies, in large industrial welders, etc., and in nuclear atomic accelerators and critical airborne radar systems.  CONSENSORs were used in Raytheon's testing of the MARS ROVER cameras.

Recovery time depends on the RH in its vicinity and the frequency and amount of condensate that was experienced in any event.  ALL condensation sensors are vulnerable to excessive amounts of condensate or other liquids on their internal sensors. 

There has been much confusion about so-called condensation sensors in the HVAC industry.

Model CG2-CM -P  or  -F
Both models provide fully isolated (voltage free)  SP/ST Normally Closed solid state contacts for systems with - or without, a Controller.    These contacts may also be used in systems where valve solenoids, etc. are controlled directly by thermostats / relays, etc.
        ALL CG2-CM SERIES INCLUDE A
        Bi-COLOR LED TO INDICATE:                                -  No CONDENSATION detected
          - CONDENSATION is occurring, or
          -  SENSOR FAULT - a really unique
                     "FAIL SAFE" feature. 
If any sensor malfunction is indicated, coolant flow is automatically stopped until the problem is rectified.  Usually, these issues can be addressed in the field.

WIRING DIAGRAMS
CONSENSORs incorporate the best "FAIL SAFE" design practices. 
Virtually all other condensation sensors on the market are actually HUMIDISTATS set to signal a coolant shut down when the adjacent Relative Humidity reaches 80% to 90% RH.
Even the more costly Dew Point based sensors are humidity dependent
