LB-715

Description

Pressure gauge LB-716P is designed for absolute air pressure measurement and a pressure gauge LB-716D is designed for measurement of differences between two measurement stub pipes placed on the outside of a device casing. They are electronic devices, stationary, of small size, powered from an outside power supply.

The device uses for measurement data from a semiconductor pressure sensor. Basing on the knowledge of calibration data stored during the calibration process in a device's nonvolatile memory (each device is calibrated separately) the microprocessor (built-in the device) counts the actual pressure measurement result. The measurement results are sent (in a digital form- current loop) from the device to a supervisory system of data collection using: a concentrator LB-731, a converter LB-486, a reading - registering panel LB-724D or (by using a passage LB-730 through the interface RS-232C) to a PC computer. The interface parameters allow on sending
data and powering the device using one two cable line of any polarity. Length of the sending line is limited only by the resistance of the cable used (the resistance of both cable conductors cannot be more than 100 om).

Pressure gauges LB-716P and LB-716D are made in few versions that differ in the scope of pressure measurement.

Each meter LB-716x can have a calibration certificate attached issued by the Air Force Technical Institute or LAB-EL Calibration Laboratory.
