A401 Electronic Crack Meter Logger

Stores up to 64,000 measurement values, depending on the memory capacity.

• Built-in memory for 16,000 readings (optional memory for up to 64,000 readings)
• Measurement and storage of the cycle (1 second to 24 hours) freely adjustable via PC software
• Freely programmable, fully automatic start-stop operation or continuous loop storage
• Integrated crystal oscillator-controlled real-time clock and real-time calendar
• Measurement range of the crack sensor: 10 mm (+/- 5 mm)
• Extended measurement range for the crack sensor, e.g. 75 mm, available as a customised version
• Resolution of the crack sensor: 2.5 μm = 0.0025 mm = 0.0001 inch
• Length of the crack sensor cable: 2 m (longer cables of up to 100 metres available on request)
• High-speed crack monitoring at up to 100 Hz can be activated
• No mechanical torsion of the sensor thanks to the complete decoupling of the stopper
• Sensor can be zeroed (tare function) and the system is started via an activation magnet
• Optional: Combined air temperature and humidity sensor (internal climate sensors) available
• No calibration of the climate sensors required
• Measuring range of the air temperature sensor: -20 °C to 70 °C
• Measuring range of the humidity sensor: 0% RH to 100% RH (dew-free)
• Resolution of both climate sensors: 0.1 °C / 0.1% RH
• Accuracy of the air temperature sensor: <0.4 °C at 20 °C
• Measurement accuracy of the humidity sensor: <3.0% RH between 20% RH and 80% RH
• Optional: Climate sensor with a measurement accuracy of <1.8% RH and <0.3 °C
• Repeatability of both climate sensors: 0.1 °C / 0.1% RH
• Long-term stability of the air temperature sensor: <0.04 °C per year
• Long-term stability of the humidity sensor: <0.5% RH per year
• Dew point calculation available via PC software (including for thresholds up to 100% RH)
• Automatic min/max monitoring for gapless recording of extreme climatic values
• Alarm output for SMS alarm system, audible alarm system, telephone alarm system, etc.
• Numerous other external sensors available for the data logger (e.g. 8 x temperature sensors)
• External connection for four sensors available on request
• Calibration certificates available on request
• Measurement data stored via EEPROM memory, even without batteries
• Powered by two standard AA batteries
• Battery life of up to two years (see configuration). Batteries can be replaced at any time
• Shock-resistant and waterproof data logger housing. Wall mounting possible (screws concealed)
• Data logger dimensions: 88 x 120 x 50 mm (HxWxD)
