New Digital Humidity Elements For 2011

Servoflo now has samples available for the following new digital humidity elements. All models have an I2C interface.


New Digital Humidity Elements


  • HYT 121 - multilayer ceramic package of 5 x 7 mm, 2.5% rH accuracy
  • HYT 221 - round stainless steel casing, SIL connections, 1.8% rH accuracy, splash water proof
  • HYT 241 - miniature model of 9.2 X 2.9 X 2.1 mm, 1.8% rH accuracy
  • HYT 321 - low cost model with protection filter, 3% rH accuracy
  • HYT 371 - low cost, 3% accuracy, no protection filter
  • HYT 939 - TO39 housing, excellent for compressed air applications, 1.8% rH

 

Data sheets and samples are now available. You may obtain pricing by contacting us.

New Pressure Transducers 

45X5 SeriesServoflo is pleased to announce the 4515 and 4525 Series of pressure transducers from Measurement Specialties. These sensors are ceramic, PCB mounted with 1/8" barbed pressure ports. Using the latest CMOS sensor conditioning circuitry, the sensors are fully calibrated and temperature compensated with a total error band of less than 1.0% over the compensated range.

The 4515 measures from 2 to 30" of water and is available with either an analog or digital output (I2C or SPI) in gauge or differential models. Similarly, the 4525 comes in either analog or digital models but has a higher calibration range of 1 to 150 psi. The 4525 comes in either absolute (above 15 psi), gauge, differential or compound.

 

See the specifications for:

 Samples are available in April of 2011. We are compiling a list of sample requests for qualified customers.

2 New LED Driver Models!
ZLED DriversWe have now added 2 new LED drivers to our line of ZMDI LED Driver products: ZLED7012 and ZLED7022

The ZLED7012  is a low noise, constant-frequency charge pump DC/DC converter that can drive up to 4 LED channels, providing a programmable constant current level ranging from 1.8 mA to 20 mA per LED channel. The ZLED 7022 is similar except that it can drive up to 6 LED channels. Both can also drive higher current LEDs because its current sinks can operate in parallel. Both enable white or other color LED applications that require uniform intensity and/or linear progressions in brightness. Ideal for small, battery component applications as very few external components are needed.

Article in Medical Design Technology

In the December issue of Medical Design Technology, Servoflo contributed an article discussing how advances in pressure sensing technology have affected design of medical equipment. Specifically, the article uses breathing applications and oxygen concentrators as examples of how pressure sensors which are lower in cost yet with more functionality improve medical equipment design and availability to more patients. The article begins on page 26 of the magazine.

Custom Pressure Sensor Design By Metallux 
Metallux now has the capability of combining its well-known ceramic pressure measurement capabilities with plastic molding for unique applications where an off the shelf solution does not meet customer requirements. These needs are especially true in medical applications where size and packaging is critical to new designs.

Please contact us if you are having difficulty finding a pressure solution to meet your requirements.  
If you would like to see your application utilizing Servoflo's products highlighted on our web site, please contact us. We would be happy to share your story.

We thank you for your interest in our products.  Please feel free to .

We look forward to hearing from you.
