Nonlinearity is the measured deviation from the best fit straight line (BFSL) across the entire pressure range. Pressure hysteresis is the maximum deviation of the output value at any pressure within the specified range when the pressure is cycled to and from the specified minimum or maximum pressure. Repeatability is the maximum variation of the output value at any pressure within the specified range over 10 pressure cycles.

FUNCTIONAL DESCRIPTION AMS 3011 combines a piezoresistive silicon chip and a mixed-signal integrated circuit (ASIC) on a ceramic substrate housed in a robust metal package. The piezoresistive silicon chip acts as pressure sensing element and the ASIC is used for amplification and signal-conditioning. The physical pressure, which is applied to AMS 3011’s pressure ports, is converted into a differential voltage signal by the sensing element. This differential voltage signal , which is almost proportional to the applied pressure, is converted into a standardized , temperature independent analog output voltage of VOUT = 0 .. 5 V by the signal-conditioning ASIC. The signal-conditioning is done in the following way (see Figure 1): At first the sensing element’s differential voltage signal is pre-amplified and converted into a digital signal using a 14-bit A/D converter (ADC). This digitized pressure signal is processed mathematically by the ASIC’s integrated microcontroller unit. To achieve a calibrat ed and temperature compensated output signal the microcontroller unit uses individual correction coefficients and a mathematical correction algorithm, which are stored in the ASIC’s EEPROM during AMS 3011’s factory calibration process . The temperature valu e needed for the temperature compensation is measured directly at the piezoresistive sensing element, too. To obtain an analog output voltage the corrected digital signal is converted back into an analog voltage by an 11-bit D/A converter (DAC). The standardized output voltage VOUT = 0 .. 5 V (or 2.5 V ± 2.5 V for bidirectional differential types) is a linear function of the applied pressure.1 It is independent of the applied supply voltage. 1 The applied pressure is the pressure difference between port 1 and port 2 for differential and bidirectional differentia l pressure transmitters. For relative pressure types it is the pressure difference between port 1 and ambient pressure and for absolute and barometric pressure types it is the pressure at port 2 (for the definition of ports see Figure 3). Figure 1: AMS 3011’s block diagram

Miniaturized pressure transmitter with 0 .. 5 V output April 2016 – Rev. 1.0 Page 5/8 www.analogmicro.de INITIAL OPERATION The pressure transmitters of the series AMS 3011 can be screw mounted in a fast and easy way using the two integrated through bores (Ø 4.3 mm) at the sensor’s metal package’s edges. The electrical connection is established using the integrated M5 circular sensor connector and a suita ble cable with female M5 sensor connector (see “additional equipment”). Pin 1 (Vs) is directly connected to the power supply’s positive output and pin 4 (GND) is connected to GND (see Figure 2). Pin 3 (OUT) can be connected to a voltmeter directly to measure the output signal voltage VOUT (referenced to GND) or a load resistor RL can be connected between pin 3 and GND and VOUT can be measured parallel to RL. The output voltage VOUT = 0 .. 5 V at pin 3 is a linear function of the applied pressure and does not depend on the supply voltage. Please ensure that the supply voltage is in the specified range of 8 and 36 V and that the power supply is able to source at least 5 mA (for RL ≥ 10 kΩ) The pressure connection is made using the package’s M5 female thread pressure ports, where a multitude of pressure fittings can be connected (see “ additional equipment ”). Depending on the type of pressure transmitter and the application one or two of the pressure ports have to be connected to the measuring media/volume. For the pressu res at AMS 3011’s pressure ports the following requirements have to be fulfilled, wherein p1 is the pressure at port 1 and p2 is the pressure at port 2 (for port definition see Figure 3): for differential pressure (type AMS 3011-XXXX-D): p1 > p2 for relative / gage pressure (type AMS 3011-XXXX-D): p1 > pambient, p1 = measuring pressure for bidirectional differential pressure (type AMS 3011-XXXX-D-B): p1 > p2 or p1 < p2 possible for absolute pressure (type AMS 3011-XXXX-A): p2 = measuring pressure for barometric pressure (type AMS 3011-XXXX-B): p2 = measuring pressure The maximum pressures (see Table 1) and the guidelines concerning media compatibility (see specification notes 7) and 8)) have to be taken into account. AMS 3011’s package is dust - and water-tight according to IP6 7. Please keep in mind that AMS 3011 is on ly dust- and watertight if the electrical and the pressure connections are established.
