The programmable sensor signal conditioner (SSC) can be used with any sensors with a Wheatstone bridge circuit.It converts a sensor’s input (i/p) millivolt signal into a standard analog signal that can be directly connected to any computer-based data acquisition system or PLC.
The i/p sensitivity of the SSC can be processed from 1mV/V to 12mV/V, and the sensor is powered by an excitation voltage between 5 and 10 Vdc.
The sensor is supplied by A1 SSC with a pre-set, regulated excitation voltage of 5, 10, and so on. The voltage signal (0.05 Vdc or 0.10 Vdc) or the current loop (40 mA) can serve as the A1 SSC’s o/p signal.
Two potentiometers can be found at the o/p end of A1 to adjust the “offset” and “span” of the o/p signal. An anodized aluminium housing protects the circuits of A1 SSC.The A1 SSC is designed to protect the environment to IP65 level.
The Global Programmable Sensor Conditioner market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Model D1 is a programmable sensor signal conditioner (SSC) designed for use with a wide variety of resistive sensors with Wheatstone bridge-configured sensing elements.
In addition to providing the sensor with either constant excitation voltage or excitation current, the D1 SSC amplifies and conditions the sensor output signals to produce the signal required by the customer for his application.
For instance, the D1 SSC’s output can be either a digital or analog signal that can be used directly by any computer-based data acquisition system or programmable logic controller.
In point of fact, the D1 SSC is able to process any input signal from sensors with output sensitivity ranging from 1.25mV/V to 20mV/V and supply the sensors with either a constant excitation voltage of 4Vdc or a constant excitation current.
Both of these options are available to the sensors.Using a computer or a specific device, the excitation current can be changed from 50 A to 750 A.
In order to meet the requirements of various systems, the D1 SSC’s output signals can be configured with a variety of options, ranging from analog signals of 4 to 20 mA, 0 to 10 volts, ratiometric signals of 10 to 90 percent Vs, and digital signals of RS485, I2C, or SPI.
The D1 SSC’s Zero output and Span can be changed at any time via a computer in a laboratory or a specific device on the job when the D1 is being used in the field.
The D1 SSC’s programmable features are made possible by cutting-edge electronics technology.
As a result, the mechanical knobs in the previous version of D1 have been removed.As a result, the D1 SSC version that is currently available can protect environments up to IP67.
The bridge sensor-specific programmable analogue signal conditioner PGA309 from Texas Instruments is voltage output-oriented. The sensor signal is amplified by the analogue signal route. With applied stress, this offers digital calibration for sensor linearization errors and errors in zero, span, zero drift, and span drift (pressure, strain, etc.).
Through a One-Wire digital serial interface, the calibration is performed. A Two-Wire connection, which is the industry standard, can also be used. To avoid manual trimming and achieve long-term stability, the calibration parameters are saved in external nonvolatile memory (usually SOT23-5)
Four 16-bit DACs, an uncommitted op amp, an on-chip temperature sensor, a 16-step programmable-gain amplifier (PGA), a 768-byte (6144 bits) internal EEPROM, and a programmable sensor excitation are all features of the MAX1452 architecture from Analog Devices, Inc. The MAX1452 offers innovative temperature compensation strategies for offset TC and FSOTC in addition to offset and span compensation. These strategies were created to offer an exceptional level of flexibility while reducing testing expenses.
The MAX1452 is offered in 16-pin SSOP/TSSOP and 24-pin TQFN packaging for the commercial, industrial, and automotive temperature ranges.
Industrial applications (such as humidity sensors, flow sensors, pressure sensors, level sensors, etc.) are well suited for Renesas’ portfolio of resistive and capacitive sensor signal conditioners, which enable high precision signal processing in both system diagnostics and high-resolution output up to 24 bits.
The SLG47004 is a mixed-signal operational amplifier, digital rheostat, EEPROM, and a large selection of analogue and digital macrocells programmable AnalogPAK IC.
This GreenPAK device’s ability to periodically adjust its rheostat value to either correct for system error sources or reconfigure circuit settings is highlighted by the unique Auto-Trim feature. To maximise power consumption performance, the SLG47004 offers dynamic Power Down management for both analogue and digital blocks.
