Honeywell FSS1500NGT

FSS - SMT Series force sensors are designed to be reliable. This low profile Surface Mount Technology (SMT) sensor allows for automated assembly on a printed circuit board, often helping to reduce assembly costs. The sensor is designed to provide precise and reliable force sensing performance in a compact commercial - grade package. It incorporates a specialized piezoresistive micromachined silicon sensing element. The low power, unamplified, uncompensated Wheatstone bridge circuit design provides inherently stable millivolt output over the force range. Force sensors operate on the principle that the resistance of silicon - implanted piezoresistors will change when the resistors flex under applied force. The sensor concentrates force from the applications, through the stainless steel ball, directly to the silicon - sensing element. The amount of resistance changes in proportion to the amount of force being applied. This change in circuit resistance results in a corresponding mV output level change. The sensor package design incorporates patented modular construction. The use of innovative elastomeric technology and engineered molded plastics results in load excitation capacities of 44 N over - force. The stainless steel ball provides excellent mechanical stability, and is suitable for a variety of potential medical and commercial applications.
