Applications and UseTop

Q:
What are some of the applications you have used temperature controllers for?
17 answers
Answers:
Onboard offshore supply vessels which have to meet BV classification. One rule states that if a transformer temp gets to an alarm temp we must initiate a propulsion slow down. We use temp controllers to monitor and alarm.
~Tom R, Testing Manager, Yangzhou, China

FeaturesTop

Q:
What would your design or feature "wish list" be for this product?
4 answers
Answers:
A way to rest PID / output on startup. If your controller is in run mode when turned on but you are not ready to start/power the heater the PID assumes it needs to give a full power output signal which is not true. Like to have an input the when pushed the output goes low so you don't give full power to the heater.
~Ron R, Technical Support, Exeter, NH
Wireless with long range sensors.
~YOUNUS LALA, SERVICE MANAGER, GLENDALE, CA
Simpler implementation
~Marketing/Sales, Algonquin, IL
Integrate with Ethernet
~Michael Lim, Marketing/Sales, Singapore, Singapore

Buying AdviceTop

Q:
Do you have any advice for people relative to buying or using temperature controllers?
3 answers
Answers:
Understand what you truly need from controller and how it operates before pinning failure on the heater. Most likely it's a controls issue.
~Ron R, Technical Support, Exeter, NH
Most of the temperature controllers are compatible and able to use one another.
~Michael Lim, Marketing/Sales, Singapore, Singapore
Touch screen
~YOUNUS LALA, SERVICE MANAGER, GLENDALE, CA

Q:
Is there any advice you want to share with users to help them avoid common errors in selection or usage of temperature controllers?
3 answers
Answers:
Understand what you truly need from controller and how it operates before pinning failure on the heater. Most likely it's a controls issue. Understand PID and that Autotune for quick responding heaters is not typically a good thing if its not fast enough to keep up with how fast the heater responses.
~Ron R, Technical Support, Exeter, NH
There are people that just need a basic temperature controller without the need for mA and voltage inputs, and sometimes you just need the PID Temp Controller without the need for Multi Inputs.
~Michael Lim, Marketing/Sales, Singapore, Singapore
Uncomplicated, device with simple programming
~YOUNUS LALA, SERVICE MANAGER, GLENDALE, CA
