Vibration switch designed to protect critical assets

The compact HS-429 enables continuous monitoring and protection of assets in tight spaces. It is designed to transmit a 4-20mA signal, features an adjustable false trigger delay of up to one minute to prevent error trips that may occur at machine start up, and is overload protected to a maximum shock of 100g.

The HS-429, which features a MEMS (Micro-Electro-Mechanical System) accelerometer integrated onto the I.C. (Integrated Circuit) microchip, is quick and simple to set up, with the maximum RMS velocity set point and response delay time easily adjustable using two rotating setup dials. It is sealed to IP67 and designed to perform reliably within a temperature range of -25 to +80°C, making it suitable for use in a range of sectors, from building services, pulp and paper, mining, and metals, to utilities, automotive, water, and pharmaceutical.

Chris Hansford, managing director at Hansford Sensors, explains: “Minimising machine downtime and maintenance costs are essential for the productivity and profitability of manufacturers. The HS-429 provides a simple, cost effective method of continuous monitoring for protecting motors, generators, engines, pumps and fans, ensuring greater machine availability and increased output."
