Ultrasonic level detectors UZS-5

The alarm devices are designed to signal the limit values of the liquid level at one or more control points in technological tanks, storage facilities, tanks in stationary conditions and on mobile objects with the output of information about the liquid reaching the limit level in the form of a discretely changing analog signal, light indication, switching relay contacts or via the RS-485 interface.

Ultrasonic level detectors UZS-5 are designed for use in automated process control systems, alarm systems for technological and emergency liquid levels, pump protection systems, etc.

Level detectors are designed to work in conditions of high and low pressures, high and low temperatures, vibrations and shock shocks, exposure to aggressive and dangerous environments, salt fog, frost and dew, electromagnetic interference, special factors, etc.

The principle of operation of signaling devices is based on various properties of ultrasound propagation in a liquid and gas. The alarms have no moving parts and do not create acoustic interference.

Main features and advantages:

unified sensor output signal (4-20 mA), with power supply along the output signal line;
independence of the sensor response level from the properties of the controlled liquid, its temperature, pressure, density, viscosity;
one one-sensor monitoring of several liquid levels (in one technological opening);
sensors with different lengths of the submerged part;
the span configuration of the acoustic path, which allows you to control the level in polluted and turbid environments;
the load capacity of the relay contacts of the secondary converter is up to 8 A;
a wide range of power supply voltages of the sensor and the secondary converter.

up to 8 (by special order, more is possible)

Length of the submerged part of the acoustic sensor

up to 6000 mm

up to 1000 m

Type of explosion protection

- intrinsically safe circuit «1ExdIICT6»;
- explosion-proof shell «0ExiaIICT6»

The number of sensors connected to the secondary converter

up to 8

Number of secondary converter level control points

up to 8

Operating temperature range of the environment of the secondary converter

from -50 to + 80 °C

Type of explosion protection of the secondary converter

intrinsically safe circuit [Exia]IIC

Output signals of the secondary converter

- relay (up to 8 relays with one group of switching contacts with a load capacity of 8 A relay contacts);
- digital via RS-485, light indication

Installation method of the secondary converter

Degree of protection of the secondary converter housing

- IP67 (wall-mounted metal housing);
- IP65 (wall-mounted plastic housing);

Scope of delivery:

acoustic sensor for one or more control points with an output signal of 4-20 mA;
secondary converter for working with one or more sensors, depending on the design;
communication cables;
sets of mounting parts (mating flanges, gaskets, welded bushings).

Separate delivery of the alarm components is possible. It is possible to supply and operate an acoustic sensor without a secondary converter with the sensor power supply from the consumer’s equipment and using standard current output signal receivers.
