WHAT IS THE CONSENSOR?

All condensation sensors on the market except the patented CONSENSOR, are actually humidistats set to 80% to 90% RH (Relative Humidity).  This means that when the RH in the vicinity of the sensor reaches that  preset level, a "condensation" signal is sent to a controlling computer, valve solenoid, etc .   Actually, condensation is not occurring at this point, and it may never actually occur at all.   The "condensation" signal is very premature.   In fluid cooling applications - Chilled beam HVAC systems for example, coolant flow will be needlessly stopped - often when it's needed most.

The more elaborate dew point sensors are similarly dependant on the immediate RH. 

The CONSENSOR functions very differently.  It incorporates a very sensitive condensate sensing element that is intimately coupled thermally to your surface of interest - a pipe for example.  So when the pipe surface "sweats", the sensing area also "sweats" simultaneously.  The integrated microprocessor circuit is programmed to signal a condensation condition when a microscopic deposit of condensate appears on the sensing element ... the same instant it appears on your pipe surface ... long before there is any threat of the dreaded condensation  "rain" or drip.

There are those applications in which condensation can not be controlled, but it needs to be monitored. Critical electronic / electrical circuits can be shut down to avoid malfunction or damage from condensate short circuits. Farmers can monitor dew occurances and duration.  


WHAT THE CONSENSOR IS NOT

CONSENSORs are not dependent on dew point, humidity, or temperature determinations. These parameters can only indicate that condensation is possible.  The instant a CONSENSOR indicates that condensation is occurring - it is ! … whether it is perceptible or not ! .. but never prematurly !! 

The CONSENSOR is not a quantitative condensation sensor. The onset of condensation is a binary event. The quantity of condensate is rarely important.   Trace amounts of condensate are almost always as detrimental as larger quantities. In condensation control applications, what's important is  to take corrective action so early that even trace amounts are prevented or eliminated immediately. In condensation monitoring or dew monitoring applications, you can record the true onset of the condensate's presence on your surfaces of interest. 

The CONSENSOR is not a water or moisture sensor.  It will not respond to humidity, water vapor or standing water.  It does not need to come in contact with the condensate to indicate the event.


THERE ARE TWO SENSING CONFIGURATIONS

 SURFACE SENSING: This is for thermally active surfaces … cold water pipes or water cooled heat exchangers, outdoor electrical or electronic enclosures, water cooled components or power supplies, refrigerator walls, exposed HVAC air ducting, shipping containers, ships hulls, etc.
For these applications, the CONSENSOR is to be mounted in close surface to surface thermal contact  with your surface of interest.

AREA SENSING: This is for use with thermally passive surfaces where the CONSENSOR's temperature is that of the local environment as is the surface of interest.   Examples will be thermally passive articles in a room, passive (or nearly passive) electronic components in an enclosure, passive items in open areas, leaves in a field, etc.  The CONSENSOR does not need to be in contact with these surfaces - it only needs to be placed where it can share their thermal environment.


GENERAL SPECIFICATIONS  for Model CG2-CM-P (or "-F")

MOUNTING: 
     Pipe mounted ("-P") configuration mounts to pipes (1/2" to 3") with cable ties. 
     Flat surface CONSENSORs (-F) mount with special double sided thermally conductive tape.
DIMENSIONS: Model CG2-CM-P- Nom. 1.5" X 1.1" X 1.1" H from the pipe surface.
CONNECTION: CG2-CM Series - nom. 10" long 4 conductor cable with stripped wires.                     
OPERATING TEMPERATURE: 5 to 65*C.
 Note: CONSENSORs can safely withstand temperatures below 0*C. 
      But, its operational charcteristics in ice or Frost (frozen condensates) have not been studied. 
      We can offer CONSENSORs that are usable up to 80*C on special order.
HUMIDITY: Not a factor.
CONTAMINENTS: The CONSENSOR is inert to ordinary dust and similar materials. But if it becomes       contaminated with hygroscopic materials that absorb moisture from humidity such as wall board     sandings, various fluids/ fumes, it may require attention. 
    ALL condensation sensor  types must breath the air in their environment, and all can be similarly    damaged if excessive amounts of water or condensate saturates their sensing element.
CONSENSORs require no calibration. 
FAIL SAFE:  Virtually any malfunction will initiate the most safe "condensation" signal, and its LED will flash a red- green,  red-green, etc.  "SENSOR FAULT" indication - a unique feature. 


CIRCUIT Modules

The CONSENSOR is a condensation sensor or a dew sensor. To be useful as a condensation control device, or as a dew monitor, the CONSENSOR's signal from its  sensing element must be amplified enough to provide a switched solid state relay contacts and a visual indication, etc. 

In the CG2-CM Series, that Circuit is integrated with the Model CG Sensor's sensing element as a single unit.


SENSOR / CIRCUIT ISOLATION:

All models are electrically isolated to >500 volts from your surface.  If necessary, approx 5,000 volts of isolation can be provided by the insertion of an optional silicone washer between its base and the surface to which it will be mounted.   That additional 5,000 volt isolating silicone washer will retard the unit's response time typically by 1 or 2 seconds.


"NORMALLY WET" APPLICATIONS:

CONSENSORS may be used in certain applications where condensate or dew needs to be present, as in certain polymer coatings manufacturing, agriculture, etc.


APPLICATIONS ASSISTANCE:

We are very applications oriented and always eager to discuss yours.

USE THE CONSENSOR (Model CG2-CM-P or -F)
FOR CONDENSATION / CONDENSATE CONTROL APPLICATIONS
OR AS A DEW SENSOR OR AS A CONDENSATION SENSOR
Virtually all other condensation sensors are actually humidistats set to signal a coolant shut down when the adjacent Relative Humidity reaches 80% to 90% RH.
​Even more costly Dew Point based sensors are dependent on humidity levels. 
      For Chilled Beams & Pipes
             For Glass & Flat Surfaces
The Patented CONSENSORs Are NOT HUMIDITY SENSORS BEING SOLD AS CONDENSATION SENSORS !!!
CONSENSORs incorporate unique "FAIL SAFE" technology.
BOTH PROVIDE AN ISOLATED Normally /Closed SOLID STATE SP/ST  CONTACT OUTPUT 
The CG2-CM Series incorporate a bi-color LED  which indicates the CONSENSOR's 3 states:
   - Condensation is not occurring   
   - Condensation is occurring, or, 
   - SENSOR FAULT - a unique "Fail Safe" feature
