Description
The Keller LEO-Record is a digital pressure gauge with a built-in data logger that records pressure and temperature over long periods. Piezoresistive versions cover −1…3 bar up to 0…1,000 bar with ±0.05% FS accuracy (±0.1% FS total error band from 0 to 50 °C), and capacitive versions cover very low ranges from 30 mbar, including differential pressure.
It stores up to 57,000 time-stamped values, at fixed intervals or triggered by events, and runs about two years on one lithium battery. Data is read out over RS485 with KOLIBRI software. The LEO-Record-Ei version is intrinsically safe (Ex ia IIC T4).
Argonmark Ltd supplies Keller instruments across Bangladesh — Dhaka, Chattogram, Gazipur, Narayanganj and the gas fields, refineries, terminals and power plants beyond. Send us the model, range, process connection, output and any hazardous-area requirement, and we will confirm the right configuration, lead time and price.
