New High Resolution Barometric Altimeter Sensor

MS5611 AltimeterServoflo is announcing the new MS5611 micro altimeter pressure sensor. With high resolution of 10 cm, this digital sensor has an operating range of 10 to 1200 mbar from -40C to +85C. The integrated 24 bit ADC provides an SPI & I2C interface.

 

The MS5611 provides pressure and temperature values that allow the user to optimize for conversion and current consumption. A small dimension of 5 mm X 3 mm X 1 mm allows for integration into small spaces including mobile devices. The supply voltage is 1.8 to 3.6V and consumes low power of 1 microamp. 

 

Typical uses include mobile altimeter and barometer systems, variometers, data loggers, watches and more. 

 

Pricing at 1,000 pieces is currently $5.64 each.

 

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

New Low Pressure Product & Pricing Guide Ready!  

low pressure sensorsServoflo is pleased to announce the availability of its Low Pressure Sensor Product & Pricing Guide.

This guide focuses on pressure sensors from 0.1" of water up to 3 psi. Models include unamplified and uncompensated to fully amplified and calibrated with digital or analog outputs.  A wide variety of packages is also explained.

Typical information for each model includes pressure range, outputs, typical applications and of course budgetary pricing, this new guide is a quick way for readers to review our wide range of pressure sensors available.

 
ZSSC3122 Low Power Sensor Signal Conditioning IC

ZSSC3122The new ZSSC3122 is a low voltage sensor signal conditioner for conversion of capacitive sensor signals into digital outputs. This new IC is configurable for capacitive sensors up to 10 pF and accepts a supply voltage of 1.8V to 5.5V.

 

It is compatible with both single capacitive sensors and differential capacitive sensors. Measured and corrected sensor values can be output as I2C, SPI, PDM or alarms. The I2C interface can be used  for a simple PC-controlled calibration procedure to program a set of calibration coefficients into an on-chip EEROM. The ZSSC3122 and specific sensor are mated digitally quickly and efficiently without the need of external devices.

 

The price for the ZSSC3122 is $2.83 each for 2,000 pieces.

The Unique HYT939 Sealed Humidity Sensor
HYT939 Hermetically Sealed Humidity Sensor

HYT939 is a welded, hermetically sealed digital humidity sensor with TO39 housing. Designed for compressed air systems up to 16 bar, the HYT939 includes a glass grommet and sinter filter.

 

Due to the humidity calibration process and special polynomial correction method, a high accuracy of �0.1% rH is achieved in the low humidity region of 0-10% rH up to 50 ppm water content. The sensor is suitable for dew point measurements up to -40C dp, such as for the quality evaluation of medical compressed air.

 

Because of its robust construction, the sensor withstands peak loading at high temperatures. Therefore, this special model is also ideal for extremely sophisticated industrial applications in drying systems as well as medical systems.

 

I2C compatible interface is standard. Pricing for the HYT939 is $30.53 each at 100 pieces.
