Tempatron designs and manufactures a range of products that serve the industrial electronics market. They inlcude timers, temperature and process control products and sensors for industry.

Tempatron from Eltime – Industrial Electronics

The product line includes Tachometer Relays, Liquid Level Sensors and Flow sensors. Solid State Relays and Proximity Sensors too. There are used in Industrial Control Panels in the Automation and Energy Industries.

They are based in UK, In 2010 Tempatron Industrial Controls became part of Eltime Ltd.

(History – The company was established in 1968 as part of the Unitech plc group, became part of Invensys plc in 1996 and was taken private by the current management in 1999. The company has since developed into a number of new areas including plastic welding equipment, data acquisition systems and the manufacture of temperature sensors)

Dual red/green display that shows the set point and the process reading. 33 x 74 panel mounting. Accepts inputs from thermistors, J, K or S type thermocouples, PT100 RTD’s. Analogue voltage or current inputs also can be used, this makes it a process controller.

Located in Plymouth Meeting, Pennsylvania, USA, Athena Controls, Inc. designs and manufactures digital and analog temperature control instrumentation for applications in the process industries worldwide, ranging from plastics and packaging to food and pharmaceuticals.

Athena Controls – Process Control

Athena offers temperature control solutions in three major areas of the control loop: panel and sub-panel controllers, SCR power handlers and solid-state relays, and temperature sensors. Power Controls, and Sensors.

The Athena 4000 is a 1/4 DIN panel mounted, short metal case enclosed controller that can be used for accurate proportional temperature control of most processes.

Athena Controls - Process Control

The controller accepts thermocouple or RTD input, and offers a choice of standard single outputs for energizing most common output devices. A single, digital filtered LED display provides visual indication of various controller functions.

(delabs Notes – The reason i have put this analog controller is, that this model is a classic that may have served the industry for more than 30 Years. This is also important for academic and lab study. Still the simplest real-time control for a industrial heating system. An Usability, Serviceability and Engineering example for control engineers to understand.)

POWER-IO was formed in order to expand the use of solid state power switching ( ssr, scr, igbt, mosfet, or microprocessor supervised solid state contactor ) technology in automation applications from 0.1 amp up to hundreds of amps.

POWER-IO – Custom and Standard Power Switching

Power control, heater contactors, solid state motor starters, lighting contactors, robotics, PLC interface i/o, and network i/o. Industrially hardened for commercial, military FCS, aerospace, test equipment, transportation, HVAC & other applications.

POWER-IO - Custom and Standard Power Switching

Custom interfaces for vac control inputs, vdc control inputs, 4-20mA inputs, Modbus communications, DeviceNet multi-drop communications and more. Current limited vdc input requirements of the POWER-IO products mean that they can interface to PLC or PC based control systems.
