Supporting Upstate New York, NY Metro, Long Island, New Jersey, and New England
Liberty controls, panels, and sensors are all designed and specified to be state-of-the-art and sized to fit virtually any application or specification. From simple electromechanical devices such as bulb and capillary style thermostats, to multi-loop electronic temperature controls, to full blown SCR control panels, we have over 35 years of experience in designing and manufacturing world-class control solutions.
From single-loop with one output to multi-loop with 9 outputs and microprocessor-based PID control, Liberty offers precisely the required level of simplicity or sophistication that your application needs.
Advanced models feature heating and/or cooling control modes, graphical/text LCD display, multiple alarm protection, programmable event outputs, customizable setup, enhanced profiling with data logging, and graphical trend recording..
Remote access is accomplished via Modbus RS-485 or Modbus TCP Ethernet.
Custom power control panels are available in many NEMA-type enclosures, for single- or three-phase load requirements, and in a variety of voltages, contactors, and SCR power controllers. SCR control panels integrate temperature controllers, over-temperature controllers, customer inputs, and SCR power control into a complete package. Liberty offers both standard package sizes and custom units for unique applications.
LEP & NEES will work with you to specify the correct temperature sensors for any application to ensure precise and accurate temperature control of critical processes. We specialize in providing custom manufactured thermocouples and RTDs specifically designed to meet individual customer requirements, as well as providing a large stock inventory of thermocouples for immediate delivery. In addition, we stock a wide range of temperature sensing accessories.
Temperature control solutions range from simple single-loop controllers with one output to sophisticated multi-loop systems capable of managing multiple heating and cooling zones simultaneously. Advanced electronic controllers can provide PID control, alarm functions, event outputs, profiling capabilities, data logging, and graphical trend monitoring. The appropriate controller depends on the complexity and precision requirements of the application.
PID (Proportional-Integral-Derivative) controllers continuously monitor process temperatures and automatically adjust output to maintain a desired setpoint. Compared to basic on/off control, PID regulation can minimize temperature fluctuations, improve process consistency, and reduce overshoot. This level of precision is especially valuable in applications where product quality or process performance depends on maintaining stable temperatures.
Custom control panels can combine multiple components into a single integrated solution, including temperature controllers, over-temperature protection devices, contactors, SCR power controllers, customer I/O, alarms, and monitoring systems. Panels are available for both single-phase and three-phase applications and can be configured to meet specific enclosure, voltage, and environmental requirements. Integrating these functions into a single panel simplifies installation and operation.
Sensor selection depends on factors such as operating temperature range, required accuracy, response time, mounting requirements, and environmental conditions. Common sensor technologies include thermocouples and RTDs, each offering different performance characteristics. Choosing the correct sensor is critical because inaccurate temperature measurements can directly affect process performance, product quality, and system reliability.
Yes. Many modern temperature controllers support remote communications through protocols such as Modbus RS-485 and Modbus TCP Ethernet. These capabilities allow users to monitor performance, adjust operating parameters, review alarms, and access process data from centralized control systems. Remote monitoring can improve operational visibility and simplify management of multiple heating processes across a facility.
