Servoflo is pleased to announce new design engineering services for custom sensor development. The objective is to be a primary resource for customers who require modification or customization of sensors. Examples include:
The AP
/AG Pressure Sensor Series are high performing gauge pressure sensors with calibration ranges from 0-25 kPa up to 0-1 MPa. With a high accuracy of +/-1.5% FS and a wide temperature compensated range of 0-85C, the AP/AG Series are an ideal alternative for those considering NXP (formerly Freescale) or Honeywell Sensors, as the AP/AG sensors are competitive on both price and performance. The AP represents the through-hole version while the AG represents the surface-mount package.
Users can order sensors with a smooth or barbed port with either 3 mm or 6 mm length. In addition, the sensors can be ordered with a specific input voltage range of 5, 3.3 or 3.0 Volts.
The new ME780 family uses a hybrid technology and Metallux's chip-on-board expertise to have signal conditioning directly integrated on top of the sensor. Together with membrane media-compatibility, the sensors offer a compact solution and precise temperature compensation. The sensor is available in many pressure ranges between 0.5 to 600 Bar, and delivers a ratiometric output of 0.5 to 4.5 VDC or digital I2C. Overvoltage, short circuit and ESD protection included.
Servoflo offers a large number of ultra low pressure sensors for under 10" H2O. Here is a short summary of some examples:
FSP1000is a flow through differential pressure sensor for +/- 1" H2O or +/-2" H2O. These sensors are fully calibrated and compensated from -5C to 65C with an analog or digital output. These sensors accept a 3 to 3.6V supply.
SM9541 &
SM9543. The SM9541 is a gauge or differential sensor with ranges from 0.15 psi up to 2 psi with temperature compensation from -5 to 65C. The output is calibrated digital I2C. The SM9543 is similar but has a lower range of +/- 0.7 psi with a differential configuration only.
AL4 has various pressure ranges from 0- 1 kPa (0.145 psi) up to 0-10 kPa (1.45 psi). With a gauge configuration, there are various power supply options including 5V, 3.3V or 3.0V. The AL4 has dual barbed ports.
Alpha Instruments has 12 different capacitive pressure sensor models in various packages including plastic, screw terminals, stainless steel, din rail, NEMA4 or LED display. Various ranges starting at 0.1" H2O. Output choices include voltage or current in either a uni or bi-directional configuration.
The FS4001 mass flow sensors are manufactured using Siargo's proprietary MEMS flow sensor and packaging technology. The sensors are specially designed for low flow rates from 0-30 sccm up to 0-1000 sccm. With a high overpressure of 5 bar (73 psi), the FS4001 can be used in a wide range of applications including
Instrumentation (such as mass spectrometry)
Leak detection
Process control
Gas flow metrology
Medical applications
The FS4001 requires a power supply of 8-18 VDC and provides an analog (0.5 to 4.5 VDC) and/or digital user interface (RS232). The calibration is generally performed with nitrogen at 20C and 101.325 kPa pressure rating. Calibration with other gases and conditions available upon request.
The Paradox of Choice When Picking Pressure Sensors
At Sensors Expo, held this past June in San Jose, David Ezekiel gave a special show floor presentation titled "
Key Factors When Selecting a Pressure Sensor". This presentation was created for those new to pressure sensors.
