Intrinsically safe (IS) pressure data loggers which can be used in potentially explosive environments such as oil refineries, offshore oil platforms and natural gas distribution.
Battery powered data loggers for recording air or liquid pressures in hazardous zones containing flammable substances. Set up a data logging procedure for immediate, delayed or event activated recording and then download the test results to a laptop or desktop computer to analyse the results and produce graphs.
- LEO Record (Ei) Capo Low Pressure Logger - Battery powered data logger for measuring and recording low range pressures. Pressure ranges from 30 mbar (12 inH2O) up to 300 mbar (120 inH2O).
- LEO Record (Ei) Pressure Data Logger - LEO Record combined digital manometer & pressure data logging instrument for recording pressures & temperatures that can store up to 57,000 readings.
- DM01 Multi-Range High Accuracy Pressure Gauge - High precision digital pressure gauge with 0.05% full scale accuracy, exchangeable pressure range modules from 100 mbar (1.5 psi) up to 400 bar (6000 psi).
- DM01-500-HD High Range Digital Pressure Gauge - The DM01-500 HD high range pressure gauge is available in pressure ranges from 0 to 600, 1000, 1600, 2000 & 2200 bar.
Intrinsically safe approved instrumentation can be installed in hazardous area zones and connected to other appropriate intrinsically safe equipment. Intrinsic safety is achieved by limiting the amount of electrical power that can enter the protected zone by incorporating zener diode or isolation transformer barriers, ensuring a specified surface temperature is not exceeded, and preventing electrical discharges which may otherwise ignite a potentially explosive atmosphere.
A pressure data logger is an instrument which incorporates a pressure measuring device with a data storage memory and firmware, or separate computer software and interface to facilitate the recording of pressure values. A pressure data logger can be setup by the user to commence recording at a certain time or event, at a preset sample rate. Once the pressure data logger has completed collecting data, the software can be utilised to analyze or transfer the data to a data file for export to another application program.
