NT04 is an Industrietechnik cable-temperature-sensor series within Regin Group. It uses a slim stainless-steel bulb and an attached cable for passive temperature measurement in liquids.

NT04 is a family designation, not one universal resistance curve. The complete article number must be selected because the available NTC and Ni1000 elements are intended for different controller input characteristics.

• Slim metal bulb supports insertion into wells or measurement points suited to the sensor diameter.
• Stainless-steel construction and an ingress-protected assembly suit liquid-temperature applications.
• Multiple passive sensing elements allow selection for a range of established HVAC and building-control input curves.
• The attached cable simplifies remote placement of the sensing bulb from the controller or terminal enclosure.

Typical uses include water circuits, storage vessels, heat exchangers, HVAC plant and other liquid-temperature points where a compatible passive input is available.

Installation must respect the medium, immersion arrangement, cable routing and the input curve configured in the connected controller.

Always specify the complete NT0420 article code. Two sensors from the NT04 family may look identical while using different resistance curves.

Confirm the controller manufacturer, nominal resistance and characteristic curve before ordering. Compatibility names in the manufacturer catalog are a selection guide and do not replace the controller input documentation.

Is NT04 a Honeywell module?
No. The official source identifies NT04 as an Industrietechnik sensor series within Regin Group. Some variants are compatible with Honeywell input characteristics, but the product brand is not Honeywell.

Can I order only “NT04”?
The complete article code is required because the sensing element and resistance curve vary.

Is a weight stated here?
No. A manufacturer-published product weight was not found, so no estimate is presented.
