Greetings!
We are thrilled to announce the Hygrosens humidity sensor line to our offering.
 
The Hygrosens humidity sensors come in three different product areas: a humidity sensing element, dew point detectors, and a humidity transmitter.  On our website, we detail a few different versions of each product area.  However, we are able to obtain all models and packages.  See below for details on each humidity sensor product area.
 
Humidity Sensing Elements KFS Series
 
The KFS humidity sensing elements are capacitive-based with excellent stability and low hysteresis.  Our website offers detailed specifications on the KFS140-D, a 2-pin sensor, and the KFS140-MSMD, which has a surface mount package. 
 
KFS140-D Humidity SensorCapacitive humidity sensors measure relative humidity and perform very well in industrial applications needing high accuracy requirements over a wide range of operating temperatures.  The sensor elements are robust, stable, KFS140-MSMD Humidity Sensorand dew resistant.  Typical applications are portable and stationery hygrometers as well as industrial applications such as HVAC, white goods, climate monitoring, and environmental monitoring systems.  A wide range of packages and styles are available.
 
Dew Point Detection Sensors by Hygrosens

SHS-A5The SHS Series of dew formation sensors are miniature, resistive sensors for detecting the onset of condensation.  The exponentially rising resistive characteristics on the upper humidity region facilitates simple signal processing and a stable switching behavior on the dew formation threshold.  The ceramic substrate can become a thermal contact on the reverse side to sense surface humidity.

 
On our website, we profile 2 models, the 2-pin SHS-A4 and the 3-pin SHS-A5.  Additional models are available.  Typical applications for these sensors include:
 
  • Building instrumentation, air conditioning, or a cool-ceiling controller
  • Moisture protection in outside directed walls
  • Ventilation control in rooms where humidity condensation is important
  • Leakage monitoring for waterproof housings
  • Brown goods (i.e. camcorder and cameras)
 

These sensors measure typically from 0-100% RH with an operating temperature range of 0-60C.

New I2C Humidity & Temperature Transmitters from Hygrosens
CON-HYTEMOD-I2CThe CON-HYTEMOD-I2C is a humidity transmitter with either a voltage or I2C output.  By combining the most modern thin film sensor technology with flexible signal processing of an ASIC, an optimum price-to-performance ratio is achieved.
 
The high quality sensor guarantees excellent accuracy, drift stability and weather resistance.  Besides the standard plastic housing, a wide variety of customer specific models are available such as stainless steel housing, with protection filter or ready-made leads.  A temperature sensor is also included. 
 
Revised Pressure Sensor Selector Tool
We have revised the pressure sensor selector tool recently.  Instead of utilizing a third party website, we are now hosting the tool ourselves, right on www.servoflo.com.  By answering a few quick questions, the tool is designed to save you time by letting Servoflo find the right sensor for your application.  We typically respond within 1 business day with detailed suggestions for your application.
 
We look forward to working with you for all of your sensing needs.  Our broad range of products allows us to help you find the best solution for your application.  Please feel free to contact us with your application questions.  
 
Best regards,
