TEMPERATURE CONTROLS

Process controllers include single, multi-loop and non-indicating controllers designed for panel mounting. PID operating modes for heating and cooling, fuzzy logic control, output protection, ramp/soak programming and digital communications are available.

STANDARD POWER CONTROL PANELS AND PERIPHERALS

Panels are off-the-shelf in NEMA 12, 7, 4X or 4 enclosures, and include integrated temperature controls and overtemperature controls. Preconfigured with SCR power controls, transformers, firing cards, fuses, etc.

CUSTOM POWER CONTROL PANELS -- CALL

Engineered with solid state controls built to the most rigid specifications and sized for virtually any application or specification. Ross & Pethtel and Chromalox can design the panel best suited for your application.

MONITORS AND OVERTEMPERATURE CONTROLLERS

Provide safety protect for your critical equpment, products, and processes. Available with alarm relay outputs, digital LED displays, and thermocouple or RTD inputs.

SCR POWER CONTROL COMPONENTS

These components are easily integrated and deliver high precision power modulation and smooth power output to electric resistance heating applications. Includes zero-crossover or phase-angle fired configurations.

SENSORS AND ACCESSORIES

Our sensors include a varity of bare thermocuouples and RTD's to the most sophisticated infrared non-contact sensors. Stock accessories inlcude thermowells, wiring, indicating meteres, timers and recorders, electro-mechanical contactors, thermostats and thermoswitches.

HEAT TRACE CONTROL SOLUTIONS

A complete control solution for heat-trace applications, such as process temperature maintenance, and freeze protection. Modular design allows user to select only needed features to minimize price and configuration.

ELECTROMECHANICAL CONTROLS AND THERMOSTATS

An ideal alternative to the Chromalox PID process controller solution. Thermostat available in a multitude of options. Other types of controls include cutouts, thermoswitches, surface mounts, ambient sensing thermostats, appliance and room theromstats, switches.
