SKF LRM2 Series Lubrication Remote Monitor

Lubrication Remote Monitor

For monitoring lubrication systems in difficult-to-access locations

SKF’s LRM2 lubrication remote monitor is designed for use with lubrication systems that cannot be checked daily due to the nature or position of the specific application. 

Compatible with oil or grease, the monitor can be used on single-line, dual-line and progressive lubrication systems. The LRM2 can communicate with a pump or group of pumps on the same type of lubrication system. LRM utilizes a SIM card to send and receive text messages via iOS or android mobile devices or via e-mail to a computer. The monitoring system can transmit alert messages to a random number of e-mail or mobile phone contacts. These contacts can be grouped based on the message type.

The LRM2 features two digital inputs and outputs and sends both low-level and fault messages. Also, the monitor can be used to start an additional lubrication cycle and can be reset by sending messages from the mobile device. In addition, you can access system information by using your web browser without having to install special software. The LRM is suitable for wind energy, railroad wayside, cable car and wastewater treatment applications, as well as other industries.

• Antenna is packed inside housing; optional external antenna can be ordered
• LRM2 module is available without housing for mounting in existing control box

applications

• Wind energy generators
• Cable cars
• Railroad (wayside lubrication)
• Wastewater treatment applications
