The W8-D40 is a wireless vibration recorder with additional environmental sensors. It uploads directly to the enDAQ cloud over WiFi after completing a recording yet this wireless connectivity can be configured to be off when desired. This model's low cost and robust aluminum enclosure makes it ideal for general purpose vibration testing in harsh environments. The W8 offers an impressive 4,000 mAh battery (our largest) to allow for the longest recording times of our sensors.

Complimentary enDAQ Pelican case included with every enDAQ® sensor order.

Battery performance is heavily dependent upon the device configuration (sensor sample rates and triggers), battery age (including charging cycles), temperature, and WiFi interference/strength. The following table provides the battery life and storage capacity of this device assuming it has a relatively new battery and it is at room temperature. When showing performance it assumes all sensors are on at the default sample rate with the main accelerometer sample rate driving performance. It also assumes wireless upload is turned OFF. If the device is uploading to the cloud after every recording, assume a battery life of 50% that listed below. With triggers, it assumes the device is in trigger mode 99% of the time. Here are some additional resources: Measurement Settings, Battery Specifications, Battery Life Estimator Tool.
Sample Rate | Storage Capacity | Continuous Recording | Main Accel. Trigger | 2nd Accel. Trigger | Periodic/Time Trigger |
50 Hz | 64 days | 11 days | 35 days | 2.8 years | |
200 Hz | 40 days | 11 days | 35 days | 2.8 years | |
800 Hz | 15 days | 10 days | 35 days | 2.6 years | |
4,000 Hz | 4 days | 8 days | 35 days | 2.3 years |
