MINING EQUIPMENT MONITORING& PROTECTION SOLUTIONS pcb.com/imi-sensors | 1 800 959 4464 ®IMI SENSORS

Mining operation involves a variety of heavy rotating machinery that is used for exploration and processing of precious metals, minerals and material extracted from the earth. This industrial machinery is subjected to moderate, and in some cases, extreme vibration levels while in use. It’s critical to trend these vibration levels to ensure equipment health reliability and to avoid unscheduled downtime. IMI Sensors offers a full line of piezoelectric accelerometers, wireless solutions, transmitters, switches, enclosures, microphones, sound level meters, cable assemblies and accessories that are...

UNDERGROUND MINING APPROVED SENSORS Mining is inherently a dangerous industry where the health and safety is of the utmost importance to the miners and their organizations. Thus, the mining industry has invested a great deal of time and money to develop safety procedures and training to assure the health of their miners. Within the United States, The Mine Safety and Health Administration (MSHA) is dedicated to “Protecting Miners” by developing regulations that will assure the health and safety of the US miners. Organizations like MSHA are also found in other countries and like MSHA, have developed...

Mining equipment reliability monitoring now requires instrumentation that is approved for hazardous environments. In addition to underground mining approved sensors (MSHA), IMI® has a full line of PdM sensors and related technologies, such as intrinsic safety barriers that, when used together, will meet CSA, ATEX, and IECEx approvals. ■ High frequency response 15 kHz (+/- 3dB) ■ High frequency response 10 kHz (+/- 3dB) TOP EXIT ACCELEROMETER MODEL EX628F01 ■ Quartz sensing element (sudden temperature change) Small installation footprint ■ IMI’s most popular top-exit low cost general purpose accelerometer...

In harsh, caustic, or high temperature areas, IMI Sensors offers a series of industrial ICP® sensors and cable assemblies that will withstand these rigorous environments. Cables and connectors made of material such as PTFE and FKM are available for higher temperature and/or caustic mining environments. Industry exclusive, ICP® sensors are available with temperature ratings up to 325 °F (162 °C). For temperatures greater than 325 °F (162 °C), IMI® has designed charge output sensors with inline electronics and appropriate cable assemblies that can hold up to temperatures up to 1200 °F (649 °C)....

Why have people risk injury and venture into unsafe areas to collect vibration data on healthy machines? IMI Sensors offers the Echo® Wireless Vibration Monitoring System that can automatically collect machinery health data in dangerous areas without having a miner venture into those areas. Using this alarm based system, personal intervention is only required when the system identifies a problem. ■ Easily integrates with legacy vibration and plant monitoring systems via Modbus® WIRELESS MONITORING OF PUMPS IN TAILINGS PONDS Barge pumps in tailings ponds are critical to the operation of a mine....

ECHO WIRELESS MONITORING SOFTWARE: ■ Vibration Alarm Panel: See your machine health at-a-glance for all vibration sensors from a single receiver, as well as machine name and location details. ■ Vibration Trend Plot: View and analyze the trend history and alarm levels of a single parameter for any sensor. ■ System Overview: See your machine health and sensor status at-a-glance in a graphical presentation for all sensors and receivers. ■ Email Alerts: Receive alerts about your machine’s health and vibration level wherever you are, so you can always be on top of the situation. This data is also...

Continuous monitoring and protection of critical assets has become a common practice in today’s mining industry. IMI Sensors meet these continuous monitoring needs by offering a series of transmitters, switches and detectors that can be integrated within a facility’s control room to monitor critical machinery parameters 24-7. ■ 24V loop powered that interfaces directly with a PLC, DCS and SCADA systems ■ Multiple ranges available ■ Peak or RMS, acceleration or velocity output options ■ Explosion proof versions available ■ Provides early warning of rolling element bearings (RFB) faults ■ Outputs...

NOISE EXPOSURE & MONITORING Mines can be a very noisy environment where employers have a responsibility to protect workers from noise induced hearing damage. To help access the noise exposure risk and verify the effectiveness of a hearing protection program, Larson Davis offers a line of noise dosimeters, sound level meters, and software to measure noise exposure. Because exposure to vibration has also been shown to be a health risk, we offer the HVM100 with all the necessary sensors to measure human exposure to vibration. HUMAN VIBRATION MONITOR MODEL HVM100 INTRINSICALLY SAFE NOISE DOSIMETERS...

ROTOR MEASUREMENTS OF DRIVESHAFT TORQUE & MOTOR TEMPERATURE An RF power supply in the receiver provides power to the primary coil of an RF air gap transformer (the stationary pickup). The transmitter receives this power by secondary coils embedded inside the transmitter housing, and provides DC power to the strain gage sensor on the shaft and to the transmitter electronics. The strain gage converts shaft strain to mV output, which is amplified, anti-alias filtered, and digitized before transmitting the data to the receiver. The receiver outputs a +/- 10 V analog signal, thereby providing a direct...
