Introduction
The Triton IT Pressure Transient data logger can detect and log pressure surge data up to 1000 readings per second without interfering with the main recordings.
During threshold logging, the logger checks the pressure signal against the threshold settings 10 times per second and once triggered starts logging data at one of the configured log rate of 10Hz, 100Hz or 1KHz.
If external power is connected the logger can sample pressure at 1KHz continuously, detect and record data at 10Hz, 100Hz or 1KHz before during and after the surge event.
The logger software can also be upgraded in the field via the IrDA communications link.

Product Help
Max & Min pressure readings
Does it help if you are looking for min and max pressure info?
Yes the software provided will allow to analyse min/max pressure info, plus much more.
External transducers
Is the external sensor capability compatible with any 6 pin transducer?
You can use any sensor with a 0/4-20mA, 0.5 to 4.5V, 0-5 / 0-10V output.
Multiple input channels
Will this be able to read multiple other transducers at once?
There are up to 3 sensor inputs available per device which can be recorded simultaneously
High sample rate logging during upset condition
We are trying to capture pressure information on a high pressure system to determine the cause of pressure safety valve activation and failure. Our existing logger captures pressure information at a rate of once per second and we are not able to accurately diagnose the issue. Ideally we would like to record pressure data only when there is an upset condition or pressure excursion at a high sampling rate?
Yes the Triton OIT would be ideal for this, since it logs at a slower rate until there is a sharp change in pressure, and then it switches to a higher logging rate, which is much faster than once per second.
Battery life
If internal power supply is included, is it a rechargeable battery or replacement of battery is needed and what battery does it use? How long can the internal power last for at 10Hz sampling rate?
The standard device has a battery fitted internally, which is non-rechargeable, but it will typically last >5 years.
External power continuous 1kHz sampling
I have noticed it has “External power option: Allows continuous pressure sampling at 1KHz”, does it means that it comes with internal power supply?
The plug in external solution means you can switch to permanent 1000Hz measurements but be aware of the amount of data this will accumulate.
1000 Hz logging rate memory capacity
I have noticed it has 2mb flash memory and take 1 million data entry. If it runs at 1000hz, does it means it will be full in roughly 16 minutes?
The Transient logger has a unique surge detection algorithm to detect peak pressure spikes and switches to high measurement rate to capture events. This is commonly used in water hammer detection applications for instance. The logger samples the pressure signal continuously at 10 samples per second until a pressure surge is detected. The logger then starts recording data at a higher speed of up to 1Khz until the surge has passed. It also stores 1000 pre-trigger readings. This means it will last a long time installed without filling the memory.
Pressure spikes on water utility system
We are working on a water utility system, doing telemetry. We would like to sample the pipe pressure at a high rate, to detect some pressure spikes with a very minimal chance of missing such.
The external power option allows to use a sampling rate of 1kHz for capturing water hammer and other pressure spikes on water mains feeds and water networks. This transient feature allows you to capture events that general purpose pressure gauges and pressure loggers would miss thanks to its unique data logging regime which switches to a higher recording rate when there is a sudden change in pressure.
