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.
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.)

Flow Meters: High Quality Mass Flow Controllers And Digital, Pipe, Or Ultrasonic Mass Air Flow Meters For Natural Gas, Oxygen, Water, And Other Liquids.
Sierra Instruments – Mass flow meters and Controllers
“Mass Flow is the quantity of direct interest whenever the molecules of the gas are the control variable in your process – such as combustion, chemical reactions, ventilation, product drying and a variety of other process applications.”
Smart-Trak – Product site focusing on Sierra’s Smart-Trak Digital Mass Flow Meters and Controllers.
“SmartTrak 100 features Dial-A-Gas® technology for true digital performance in up to ten pre-programmed gases with the same unit (gas type list can be programmed on request). Another unique factor of the Model 100 is the pilot module which replaces expensive control/readout electronics and is available mounted to the face of the instrument or in a convenient hand-held version.”
