We first started producing sensing solutions for large medical devices in 1981 and pride ourselves on producing best in class solutions for companies such as GE, Siemens, Philips, Accury, and Intuitive Surgical. Over the years we have invested in expanding our product solutions in the sensor industry and today offer a variety of options to suit our customers needs. From large scale collision sensors to small wearable flexible bio sensors our team has the experience to solve your sensing problems. Today we serve multiple industries around the globe.
What is a collision sensor?
A collision sensor is a device to detect or avoid a collision with another object. Typically used in medical applications, collision sensors can protect patients, operators, and equipment from sustaining damage or avoiding a Collison altogether. In a lot of applications, the sensor is used to stop a moving device as it would come into contact with a patient to prevent injury. Collision sensors can be pressure sensitive panels, capacitive proximity sensors, or a combination system using multiple technologies. For more information please visit our Collision Sensor Page.
Big SwitchTM
The Hall Company’s Big SwitchTM is an oversized touch surface that can range from 1 square inch to multiple square feet of active surface area. The Big SwitchTM is designed to stop a device upon contact with an object to minimize injury or damage and limit liability. The Using proprietary technologies developed over decades of product offerings, The Hall Company can ensure exact activation pressures from a few ounces to several pounds maintained consistently over the entire active area. These solutions can be applied to a variety of surfaces and to complex curves. Multiple mounting options are also available to work in any environment. The Big SwitchTM can be a single or multizone sensor allowing very complex sensor arrays for any product shape, size, or dimensions. Some other applications the Big SwitchTM For more information please visit our Collision Sensor Page.
Proximity Sensors
Proximity sensors are capacitive sensors that utilize the human body’s natural capacitance properties to detect a body prior to a collision. In essence, Capacitive sensors use the electrical properties of the human body to detect it is there. These sensors can detect a collision with a device prior to the collision, allowing the opportunity to avoid the collision altogether. The distance range variations are customizable to your application, and the system can also be used to gage distance from an object. In addition to avoiding a collision altogether, a device can also use this type of sensor to slow a machine down as it comes closer to a patient. Another option would be the ability to follow the contour of a body while staying at a consistent distance range. For more information please visit our Collision Sensor Page (link). Some other possible uses for proximity sensors are hand free operation of a device such as a dispenser, hands free door opening, detection of a conductive object in a process, or the ability to know if an operation is complete by a conductive item being in place. There are many other possible applications for this technology and our team of engineers is ready to assist you with your project.
Liquid Level Sensors
Most liquids also have a capacitive value to them. This gives the ability to have a sensor that can detect the level of most liquids in a vessel, tube, or other type of fluid holding application. As capacitive sensors achieve a high degree of sensitivity, it is possible to get very precise readings of a liquid. A printed capacitive sensor can be applied to a non-conductive holding vessel to read what the level of the liquid is. Some applications of this technology include; precise measurement of a liquid dispensed in glass beakers, when a fluid is present or not present in a tube or piping, when a certain mixture is in a tube, and when a tank is filled to a certain level. There are many other possible applications and our team is ready to help you develop your sensor.
Electrodes and Biosensors
Printed electrodes and biosensors are a quickly growing field in today’s medical and consumer markets. The Hall Company has the experience producing high quality medical sensors to assist your team with your project. We offer sensors printed with conductive inks in a wide variety of size options and patterns. We can also print on a wide variety of substrate materials including stretchable plastics and heat transfer materials that can be used for next generation garment applications. Some examples of these types of products include:
