Types of Sensor Accessories
Sensor accessories provide components to hold, position, and connect sensors. They are available in a variety of lengths and types to meet different application needs.
NIBIB-funded researchers are developing smart textiles that can detect DVT (deep vein thrombosis), a life-threatening condition where blood clots form in the legs and travel to the lungs.
Power supply
Sensors require a source of energy to respond to environmental input and Microwave Sensor Supplier generate output. A power supply is the source of this energy and is available in a variety of types, lengths and connectors to fit a range of sensors and environments. A properly selected power supply can help ensure your sensors operate correctly and avoid unnecessary power-related issues.
Sensor mounts, cables and adapters are sensor accessories that hold or position a sensor and connect it to other equipment. They are typically made of materials that can withstand a wide range of temperatures and conditions. They are used in a number of processing and automated environments, such as mechanized or robot-assisted manufacturing, pipelines and scientific measurement stations.
Power failure sensors are a useful sensor accessory for monitoring the status of a primary power source. They can provide real-time alerts when a power source goes out and notify users when the source is back on. They are commonly used to monitor backup generators, 3 phase or UPS sources and single phase AC power supplies.
Accelerometers measure changes in gravitational acceleration and are often used for vibration, tilt or speed measurements. A metering amplifier can be connected to an accelerometer and used to convert an analog output from the sensor to a digital signal that can be processed by a computer for data logging or reporting.
Adapters
Sensor accessories include mounts, cables and adapters to hold or connect sensors to other equipment. These accessories help ensure the proper position of sensors and their ability to collect data accurately. They are often designed for specific environments and adhere to specific regulatory requirements and quality standards.
For example, the AA01 CO2 calibration accessory allows you to use the same sensor for a field calibration even if it has been in service for a long time. This kit comes with everything you need to calibrate your Veris Industries CO2 sensor including calibration gas, a gas regulator and tubing.
Another sensor accessory is the FSA adapter board that lets you use a third-party processor development board to control and stream image information from the sensor module ecosystem. These boards work piggyback with the sensor modules and convert their signals to MIPI CSI-2 (D-PHY) image data for faster processing.
The CA adapter cable series is used with Beamex MC6 family calibrators to support the connection of non-Beamex Pt sensors to their R2-ports. These cables allow you to use a variety of sensors or transmitters with your MC6 calibrator and they provide a battery-saving switched input to extend the life of the external batteries. They also feature a 0-5 V output and can be left as an open-drain output. They can also be configured to produce a digital RPM signal compatible with most 2-wire Hall effect speed sensors such as those found on automotive crankshafts, camshafts and transmission shafts.
Mounting
Sensors can be mounted in a variety of ways, ranging from simple adhesives to specialized clamping systems. All of these options need to be properly selected and used to ensure accurate measurements.
For permanent applications where drilling is not possible, the use of an adhesive mounting system can be the best solution. A choice of adhesives includes VersiLock 406, Loctite Depend and Liquid Metal, all of which are designed to withstand high frequencies. Ideally, the surface to which a vibration sensor is mounted should be as flat as possible, clean and free of oil and debris. In addition, a light coating of a lubricant can aid in the transmissibility of higher frequency vibrations. This can be accomplished by using a silicone vacuum grease, heavy machine oil or bees wax.
A more durable alternative to adhesive mounting is the use of a sensor holder. This holder is constructed of an axis body with a T-slot and cutouts on both ends for inserting fastening nuts. This provides a more stable, more rigid mount and can be positioned in the center of the sensor to allow for easy access to the calibration adjustment port. It can also reduce the number of components needed for positioning a digital sensor, which simplifies assembly and makes it more resistant to misalignment and movement.
Thermowells
Thermowells protect temperature sensors from corrosive liquids, high material velocities, and extreme pressure. They extend the sensor’s life, enable it to be retrieved for calibration, and prevent contamination. They can be threaded, flanged, or welded into piping or vessels and are available in different materials and sizes for a range of applications.
The thermowell’s wall must be thin enough to swiftly transport heat from the process to the sensor without warping or failing due to mechanical stresses and pressures. It must also be thick Sensor Accessories enough to withstand chemical attack and erosion from the environment. Typically, stainless steel is used for these purposes because it is affordable and resistant to corrosion.
Thermowells are practical additions to existing or new sensor installations. They can be used in a variety of industrial environments, including power generation, pharmaceuticals, refineries, and food processing. They can improve the accuracy of temperature measurements and allow them to be taken in places where drilling holes in pipes is impractical or dangerous, such as a confined space. Additionally, they can reduce labor costs because a worker doesn’t need extra protective equipment or to shut down the system to replace the sensor. This also makes them a useful tool for sanitary Clean-In-Place 3-A approved systems. Moreover, they can be removed from the system without draining or depressurizing the process.
