SENSORS

Sensors for mining

Sensors for mining They provide information about the status of machines, conveyors, and the course of selected technological processes. Depending on their design, they can measure physical values, detect movement, or confirm the presence of a specific material.

Elektrometal's offering includes sensors for a variety of tasks, from measuring the temperature of machine parts, to monitoring conveyor belt movement, to detecting the presence of ore. This allows devices in this category to serve as a source of information for control, signaling, and automation systems used in mining facilities.

The machine temperature can be a signal to the control system

The offer includes two solutions designed to measure the temperature of machine parts. EM-DCT-10 – two-state temperature sensor performs measurement in a two-state system, while EM-ACT-10 – analog temperature sensor transmits information in analog form.

These are not two variants of the same device, differing only in name. The method of transmitting temperature information is different, which is important when the sensor is used with a specific control or monitoring system.

Conveyor movement control

It performs another function intrinsically safe CRI-97/1 motion sensor The device is used in mining plants to control the movement of a conveyor belt and works in conjunction with a local UML microprocessor device.

In this case, the information relevant to the system is not the temperature or the presence of material, but the movement status of the installation element. The sensor therefore plays a specific role in the conveyor's operation monitoring system.

Detection of the presence of excavated material

COU-22 – excavated material presence sensor detects the presence of material on the conveyor belt. Depending on the design, it can be used to monitor excavated material on the return or transport belt.

In one embodiment, the device may be part of the SDRT-23 conveyor belt cut detection system or may be compatible with the conveyor control system or signaling and interlocking systems, such as the ELSAP-05 or UGS-10. In another embodiment, information about the presence of excavated material may be used to control the conveyor haulage.

This clearly demonstrates the role of sensors in mining automation: they measure or detect themselves, but the value of this information is often revealed only after it is transferred to a device or a superior system .

Sensors as a data source for automation

A sensor should not be considered solely in terms of the quantity being measured. It is also important how it transmits information and with what system it should cooperate An analog sensor performs one task, a binary device another, and a sensor detecting movement or the presence of excavated material performs another.

Therefore, this group is directly related to the offer control and automation for mining An example of such cooperation is the controller UML-05 , which can read the states of binary sensors and use them to control the operation of conveyors.

Sensors are one of the groups in a wider range of products. equipment and systems for mining Depending on the function of the installation, their signals can also be used by solutions in the field of visualization and other systems supervising the course of technological processes.
