Clamp-On Flowmeter

The Prosonic Flow W 400

The Endress+Hauser, Greenwood, IN, Prosonic Flow W 400 clamp-on and I 400 insertion units provide comprehensive process monitoring with long-term cost efficiency and extensive diagnostics.

Prosonic Flow W 400 can be mounted on a wide variety of pipe types and materials with or without lining, including metal — e.g., steel or cast iron — plastic, glass-fiber-reinforced plastic, and composite materials. A maintenance-free contact medium, called a coupling pad, provides optimum sound transmission between sensor surface and the pipe, and the resulting high signal strength ensures stable measurement results and long-term reliability.

These clamp-on flow sensors are available in multiple ultrasonic frequencies ranging from 0.3 to 5 MHz, optimized for application pipe size, pipe material, and fluid.

Smart Proximity Sensor Chip

The SPX-1 smart proximity sensor

Starrycom Sensing Technologies Inc., Westford, MA, is announcing the release of its SPX-1 smart proximity sensor — a mixed signal VLSI system on chip. Its dual tank oscillator analog front-end design guarantees differential detection, high sensitivity, temperature tracking, and good noise immunity. Proximity sensors built with SPX-1 smart chips can achieve high temperature stability through the IC's autonomous machine learning algorithm. It consumes less than 2 mA current and can be configured for both three wire and two wire proximity sensors. In both cases the sensors are plug programmable, meaning no additional wires or pins are needed for programming and calibration, which can be done after the sensor is fully assembled and encapsulated. The SPX-1 can also be used for high-end capacitive proximity sensor design. The IC's dual tank oscillator design can improve noise immunity, one of the major problems in capacitive proximity sensor development.

Battery Management Solution

BaMoS captures detailed battery data.

InnovationLab, Heidelberg, Germany, announced BaMoS, its innovative battery monitoring solution for automotive applications. It uses ultra-thin printed pressure and temperature sensors to capture detailed battery data down to the individual cell level, which can be used to extend battery lifetime by up to 40 percent. Detailed, cell-level pressure and temperature data are obtained from the ultra-thin printed sensor foils that can be placed between individual battery cells. As battery cells expand and contract during the charge-discharge cycle, a pressure-sensitive foil can monitor this ‘breathing’, to measure the state of charge, detect any irregular behavior, and prevent overcharging. Both the pressure and temperature sensors can be customized in terms of size, resolution, and substrate material to meet the particular needs of a customer.

High-Temperature Displacement Sensor

The NT-HT-1000 Linear Displacement Sensor

NewTek Sensor Solutions, Pennsauken, NJ, is offering a customized version of its high temperature LVDT position sensor for material testing in environments with extreme pressures and temperatures. Configured to operate in temperatures exceeding 1000 °F (538 °C), the NT-HT-1000 Linear Displacement Sensor is used for materials testing in autoclaves and material deformation testing in labs and nuclear applications. Constructed of special high-temperature materials, the customized AC-operated LVDT features a 1” diameter stainless-steel housing that protects coils from hostile media.

The linear position sensor has a 3000 psi (207 bar) pressure rating and linearity of ± 0.5% of full range in the most rugged environments. The units provide a ratiometric output for reduced thermal error and stability over changing temperatures.

Torque Sensor

The sensors use a four-element strain gauge bridge.

Sensor Technology (Wroxton, Banbury, Oxon, UK) has extended its range of torque sensors with the TorqSense SGR530/540, which has the sensing head and electronics in separate housings. This has two advantages: the sensing head can fit into very confined spaces, and the electronics can be located in a position where they are protected from physical damage, dust, dirt, moisture, electromagnetic forces, etc.

These sensors use a four-element strain gauge bridge. The gauges are affixed to the drive shaft; each measures the deflection of the shaft in a different direction as it rotates under load. The electronics collects readings from all four gauges and calculates the torque value.

These sensors can also accurately record transient torque spikes. The increasing need for accurate track and trace data has led to the need for the more detailed measurement and analysis, which is now available.
