Dear , 

Our November newsletter is here! This month we have the following items to share with you:
  • Samples are available for the new Fujikura AP2/AG2 as well as for new sensors AP3/AG3 & AP4/AG4
  • A thermal flow sensor die has been added along with a mass airflow sensor for MAF systems
  • Review the M Series of micropumps by TCS
  • The addition of 5 humidity sensors
  • A new DC-DC buck converter IC, ZSPM4022, helps optimize power usage in your design
NOTE, our office will be closed for the Thanksgiving holiday on November 28 and 29. Please plan your deliveries accordingly.

If you are unsure of your needs or would like an immediate discussion about your application, the best use of your time is to either call us at 781-862-9572, email at [email protected], or use our contact us page.
Pressure Sensors
New Fujikura Pressure Sensors - Samples Are Here!

In a follow up from last month's announcement about the AP2/AG2 pressure sensors from Fujikura, we are pleased to announce that samples are now in stock at Servoflo, and production runs have begun at Fujikura.

The AP2/AG2 sensors have a calibrated, temperature-compensated output in various ranges from 0-25 kPa up to 0-1000 kPa. 0 to -100 kPa vacuum is also available as well as custom/modified pressure ranges to measure anywhere from -100 kPa to 1000 kPa.  With high accuracy of 1.5% full-scale, this is a state of the art pressure sensor yet extremely cost effective.


Additionally, new models are now available for sampling:
AP3/AG3 pressure sensors are similar to the AP2/AG2 but include threshold detection.

AP4/AG4 pressure sensors have a digital output.

Both the AP3/AG3 and AP4/AG4 will begin production in 2014.

If you are interested in a sample, please contact David Ezekiel at [email protected].
Mass Flow Sensors
Mass Flow Sensors Added

Servoflo has added 2 new items to our mass flow sensor line.
 
PTFD10 Thermal Flow Sensor Die First, we have added the PTFD10 Thermal Flow Sensor Die. The PTFD10 measures the flow of a liquid or gaseous medium across the surface of the die using the Thermo transfer (Calorimetric) principle. It provides the sensing core for a wide range of air flow applications such as mass air flow sensors, air mass meters for engine air-take control, air velocity sensors, thermal differential pressure sensors. Additionally due to its innovative robust micro-structure, the PTFD10 is uniquely suited for liquid flow applications such as diesel fuel meters and disposable liquid micro-flow sensors for medical devices. 

Next, we have added the PMA1000 Mass Airflow Module for combustion engines. The PMA1000 series is designed to be integrated into MAF sensors for OEM and aftermarket applications. A typical MAF sensor consists of a main housing that connects to engine air-intake passage, and a plugin sensor that incorporates a sensor element and circuitry. The PMA1000 caters to those OEM customers who have their own housing design and are looking for high performance, robust and economical sensor elements and circuitry.

The PMA1000 consists of a thermal flow sensor die, micro-controller based signal conditioning circuitry, and custom packaging to fit a target MAF sensor's form factor. Posifa also provides PC-based calibration software to match PMA1000's output to the target MAF sensor's characteristic curve.

Don't forget about other mass flow sensors by Posifa:
PMF-3000 Series
PMF200010-2000 sccm
PMFc3000: 10-2000 sccm 
PMF4000: 50-300 slm

These sensors are fully calibrated and compensated with a linear voltage output and fast response time. 
Micropumps
M Series of Liquid Micropumps

Servoflo is pleased to announce the M Series of high performing miniature pumps. Designed for delivering small amounts of liquids, these centrifugal-based pumps are extremely small and quiet. 4 models are available now:

  • M100: 0-400 ml/min, 28 mm x 14 mm x 14 mm size
  • M200: 0-700 ml/min, 28 mm x 14 mm x 44 mm size
  • M400: 0-2600 ml/min, 41 mm x 26 mm x 25 mm size
  • M500: 0-12 l/m, 62 x 32 x 30 mm size
TCS Pump

Viton seals are standard, with options for alternative seal materials and wetted parts to make them resistant to most chemicals and solvents. Waterproof and submersible versions are available.

 

The pumps use push-fit connectors designed for 3.2 mm tubing. A 220 mm electrical fly lead is fitted as standard. A wide power supply range of 1.5 to 6.5 VDC can be used for the M100 & M200 pumps. Both the M100 and M200 Series are brushless pumps while the M400 is brushed and has an internal controller. In addition, the M400 accepts a 3-12 VDC supply.The M500 is brushless and delivers extremely high flows in a small package size.

 

The M Series of micropumps deliver quiet, pulseless smooth flow for a wide variety of liquid applications, including medical devices, fuel pumps, fuel cells, industrial applications and much more.

 

Pumps for air/gas are also available.

Power Management/LED Drivers
ZSPM4022 DC-DC Buck Converter - NEW!

 

The new ZSPM4022 provides high-efficiency DC/DC conversion for all load ranges, with the capability to automatically run in continuous or discontinuous modes based upon load requirements. High efficiency at low load is accomplished by supporting discontinuous mode operation where the regulator shuts down all non-essential circuits and minimizes the supply current draw. During discontinuous mode, the total power supply current is only 450�A, allowing the regulator to achieve high efficiency in light load applications.

 

The ZSPM4022 offers a full suite of protection features to ensure protection of the IC during fault conditions. These include under-voltage lockout to ensure proper operation during power-sag conditions; thermal shutdown; internal soft-start to reduce inrush current; foldback current limiting; and "hiccup" mode short-circuit protection. A power good (PG) output is also included to allow simple sequencing.

 

The highly integrated design of the regulator enables improved design cycles, lower bill of materials costs, and savings due to the small package footprint. Applications include server, telecommunications, storage and consumer devices.
