It is an all too common paradox: you need to capture transient events at a high sample rate, but the events of interest are erratically spread over a long period. The OM-CP-PRTRANS pressure recorder can solve your problems. It samples up to 100 Hz (10 ms) but it will only trigger on pressure limits that you set beforehand. You can start the trigger on high or low thresholds and end the trigger after either a chosen number of samples, or when the signal crosses over your stop threshold. The device can record up to 255 events and take as many as 262,143 pressure samples. It also shows up to 32 samples of 'pre-trigger' data so that you can learn what caused the trigger in the first place.
The OM-CP-PRTRANS is a battery operated unit with a standard 1/4 NPT for easy coupling to your pressure systems. It is also completely submersible and the stainless steel sensor can measure the pressure of most common fluids and gases. The non-volatile memory will retain valuable data even if the user-replaceable battery becomes discharged. The OM-CP-PRTRANS is your solution to the transient pressure problem.
