Temperature Controllers & PID

Temperature controller price on Voltkart: digital controllers from ₹1,030 and PID controllers from ₹1,330, including GST. The table below lists every model by panel size (48 × 48, 72 × 72, 96 × 96 and 48 × 96 mm).

A temperature controller reads a sensor (J/K thermocouple, PT100 RTD or NTC) and switches its output to hold a set temperature. They are used on ovens, furnaces, heaters, packaging machines, extruders and chillers. Prices checked 6 October 2026. Reviewed by Amit, Voltkart.

How to choose a temperature controller

• Panel cut-out: match the existing size (48 × 48, 72 × 72, 96 × 96 or 48 × 96 mm) when replacing a controller.
• Sensor input: J/K thermocouple, PT100 RTD or NTC, the same as the sensor on your machine.
• Control action: on/off for slow, simple processes; PID for tighter control.
• Output: relay for a contactor, SSR drive for a solid state relay, or 4–20 mA for an SCR power controller.
• Supply voltage: check the product page; most models run on 230 V AC and many accept a wide range.

Frequently asked questions

What is the price of a 48x48 temperature controller?

On Voltkart a 48 × 48 mm digital temperature controller starts at ₹1,030 (Selec DTC503), with the Multispan TC-49 at ₹1,035 and Swastik TC-48 at ₹1,106. A 48 × 48 PID controller starts at ₹1,330 (Swastik AK6-ATS-100); Selec PID500 models are ₹2,300 and up. All prices include GST.

What is the difference between on/off and PID control?

An on/off controller switches the heater fully on below the set point and fully off above it, so the temperature swings around the set point. PID control varies the output continuously to hold the temperature steady, which suits ovens, extruders and packaging machines. More in temperature controller vs PID controller.

Which output should I choose: relay, SSR or 4–20 mA?

A relay output switches a contactor or small load directly. An SSR output drives a solid state relay for fast, silent heater switching. A 4–20 mA output feeds a thyristor/SCR power controller or a drive.

Which sensor does a temperature controller need?

Match the sensor already on your machine: a J or K thermocouple for most heaters and furnaces, a PT100 RTD for more accurate lower-temperature work, or an NTC probe for chillers and cooling. Check the input types on the product page.

Which brands are genuine and which is Voltkart authorised for?
