Temp Controllers

Temperature Controllers and Heat Sensors

Hotco stock a large variety of temperature controllers including thermostats, regulators, thermocouples and more. Our aim is to have all the temperature controllers and related products we use in manufacturing heaters also available to our customers.


Thermostats

among our most popular temperature controllers are bulb-type thermostats which include mounting screws and dial knob.

Power / Energy Regulators

Also referred to as “Simmerstats”. These temperature controllers regulate the temperature by regulating the power.

AM25351 Power regulator set up in PVC enclosure with 3 pin plug and GPO

Electronic Temperature Controllers

Hotco offers a quality range of electronic temperature controllers to help fine tune the control system of your heating system. Our range offers our customers a great variety of sizes and configurations to replace any existing temperature controllers or as an integral part of a new control system.

We also manufacture complete control cabinets for large heating systems either as a compliment to a system supplied by Hotco, or as an upgrade to an existing one.

Here are some of the features our temperature controllers offer:

  • Fuzzy – PID Control
  • Standard DIN sizes available
  • Ramp rate & timer functions
  • Highly configurable
  • 4-20mA output options
  • Multiple alarm modes available
  • Manual control
  • Three level software access
Order Code Size (mm) Display Output
AM31249 48 x 48 Digital Relay with Type J or K input

Thermometers and Other Devices

Along with temperature controllers, we also assist in remote measuring devices including:

  • Hand held “INFRA-RED” thermo-measuring instruments
  • Hand held DIGITAL thermometers
  • Specialised probes to suit hand held digital thermometers

Solid State Relays

Order Code Description
AM25352 Voltage Output, suits 12 – 30 V SSR
AM25353 Relay output, suits contactor or 240V SSR

Temperature Sensors

Hotco manufactures a large range of thermocouples to suit almost any requirement including different shapes for different applications:

  • 45°C and 90°C angled probes
  • Ring sensors – for barrels, nozzles and pipes (Specify diameter)
  • Shim Type – for barrels and nozzles (Specify Diameter)
  • Eyelet Type
  • Leaf Style – Fits under heaters for surface sensing – shim brass 10mm x 20mm
  • Threaded Button Style – for screwing into threads (Specify thread and length)

We also carry an excellent range of standard K and J thermocouples in stock for your convenience. Stock thermocouples are supplied with stainless steel 3/16Ø 1.125″ long sensor and stainless steel braided leads.

Mineral Insulated Sheathed Range (MIMS)

MIMS thermocouples consist of 2 conducting materials (Types K, J &T) compacted into a tube (probe), normally 310 stainless steel and insulated with fine magnesium oxide. Supplied as standard with 2 metres of metal braided leads, they offer 3 advantages over the standard type:

  1. The probe can be made in very small diameters
  2. The whole thermocouple, though semi-rigid, can be bent to suit most applications without impairing performance
  3. They have a higher temperature handling capability.
Order Code Description
AM23381 Type J – 1.5mm Ø 150mm long
M23382 Type K – 1.5mm Ø 150mm long
AM23383 Type J – 3mm Ø 150mm long
AM23384 Type K – 3mm Ø 150mm long
AM23385 Type J – 6mm Ø 150mm long
