Can I connect third party equipment?

Yes, if you have upgraded to the full Machine Sentry® platform.

Globally Supported Sensors

With the release of the version 2.5 of the Machine Sentry Android Application, AVT are pleased to announce that two additional sensors are supported in the Machine Sentry System:

Tandelta Oil Quality Sensor via the Tandelta OQD Express (OQDe) Display

Tandelta produce a range of oil quality sensors which allow the condition of oil to be monitored in-situ without the need to extract a sample and send it to an oil lab. The sensor continually analyses oil in real-time while the equipment is in operation and provides an accurate statement of oil condition. Any wear or contamination is instantly detected, measured to an accuracy of 0.001%, and reported.

If the sensor is connected via the Tandelta OQD Express display Machine Sentry can connect to it and get the most recent reading. With this configuration, only “live” readings can be collected, ie at the time of connection due to limitations with the Bluetooth support of the Tandelta system. The Machine Sentry Gateway can be used to collect the data far more frequently than a manual collection via the Android device however.

CTC WA102-1A Transmitter for AC312 and AC314 Accelerometers

This device is a small Bluetooth adaptor that fits to the top of certain “low power” accelerometers in the CTC range, which allows a time waveform collection to be triggered via Bluetooth and the data downloaded. Like the Tandelta oil sensor above, the sensor will only take a reading on connection (there is no on-board storage for multiple readings).

Unlike the Machine Sentry fixed sensor, this device is single axis only, and can only take around 2000 readings before the battery is depleted and it must be replaced, however it has a higher max temperature range than the machine sentry fixed sensor at 85 ⁰C and can go even higher if an extension cable is used between the sensor and the adaptor (the accelerometers themselves are rated at up to 125 ⁰C).

Additionally, the sensor is capable of sampling at a higher sample rate than the machine sentry fixed sensor, with a maximum F-Max value of just over 15 kHz, compared to 8 kHz for the fixed sensor.
