Shock and Vibration Data Loggers
Pacific Sensor Technologies introduces a complete range of shock and vibration data loggers from MadgeTech.
The MadgeTech range of shock and vibration data loggers are portable stand alone battery powered devices designed to record environmental variables such as shock (g-force; impact/acceleration), temperature, humidity, and pressure.
Recording shock using the Shock101* data recorder is often adequate in many cases such as shipment monitoring, or laboratory/drop testing. However, recording temperature, humidity, and pressure, gives the UltraShock added versatility. In addition, these data loggers record the vector sum, giving the user the overall acceleration data of the goods being monitored.
Using a built-in semiconductor (MEMS) accelerometer, various models of the UltraShock and Shock data recorders can sense accelerations with ranges of ±5g, ±50g, and ±100g. This type of sensor is commonly used for a variety of industries, including electronics, mining, industrial, aerospace, military, automotive, and safety-critical processes.
Typical applications examples for this type of equipment include;
1 - Mechanical Stress
A sensitive microscope with a lever arm is determined to support a maximum mass of 250 newton’s on the microscope end (opposite the base). The user knows the microscope has a mass of 15 kilograms. While this microscope was being shipped, the microscope end was subjected to 3.4 g’s. The user wants to determine the amount of force that was applied to this microscope to determine if it had been damaged. In this case, the user is solving for force. So, F= mg = (15kg) (3.4g X 9.8 m/s2=33.2) =499.8 Newton’s (kg X m/s2). Upon downloading the data for this application, the user would be able to determine the exact time and data value of which this microscope was subjected to 3.4 g’s.
2 - Shipping
Qualifying a new shipping company is a perfect application for an UltraShock. An UltraShock recorder is being used to record the shipment of military ordinance that is sensitive to temperature, pressure, humidity, and shock. The ordinance has the following maximum specifications: temperature 55°C; pressure 25 PSIA; relative humidity 90%, shock 10 g’s. The ordinance appears to have arrived safely at its destination, and the personnel at the site remove the UltraShock to download the data. Upon downloading the data, the personnel find that the shock, humidity, and pressure are all within specification. However, the ordinance was exposed to a temperature of 57°C. The user can now conclude, based on the UltraShock data, that this shipping company is not adequate for shipping military ordinance.
