02 / START WITH THE APPLICATION

Your equipment.
Our starting point.

The right solution starts with the place you need to measure. Explore a few of the questions that shape a temperature probe.

01

Heating, cooling & HVAC

Air, water or pipe surface? Define the measuring point, temperature range, moisture exposure and controller input together.

02

Motors, generators & transformers

A stator slot, a winding or an accessible housing? The position, insulation and assembly sequence make the difference.

03

Food equipment & process machinery

Think about insertion depth, cleaning, mechanical access and the process connection. Suitability is confirmed for the complete assembly.

04

Connected equipment & electronics

The sensing element is one part of the signal chain. Review the input, interface, wiring and electronic integration together.

03 / BUILT THROUGH COLLABORATION

From your first sketch
to your next series.

A clear route from the application to the assembly. We work through the details with you before the specification becomes production.

The right questions come before the final specification.

01

Define the need

Your application, measuring point, constraints and quantities. A drawing or a conversation is a good place to begin.

02

Review the technical proposal

Agree the construction and sensing technology, with a quotation built around the project.

03

Validate prototypes & pre-series

Test the proposed assembly in your equipment and review any adjustments before moving forward.

04

Move into production

Launch against the approved specification, agreed quantities and confirmed delivery plan.

A FAMILY STORY. SINCE 1987.

An engineering mindset.
A human connection.

GUILCOR’s story began with thermal protection for electric motors. Today, that application-first approach connects our sensing expertise with projects around the world.

05 / A FEW THINGS TO KNOW

A clearer start.

Tell us about your project ↗
What is the difference between a sensor and a probe?

The sensing element provides the temperature-dependent electrical signal. The probe is the assembly that positions and protects it: tube or housing, mounting, cable and connection. Both need to suit the application.

What information helps you prepare a quotation?

Tell us what you need to measure, the operating temperatures, dimensions or mounting, the sensor or controller input, cable or connector, and quantities. Attach a drawing if you have one. Unknown details can be discussed with our team.

Can we develop a custom probe or electronic assembly?

Yes. Start with your application and constraints. The scope may involve a probe construction, a sensing element, or a separate custom PCBA project. Technical review, prototypes and validation define the route to production.

How do we confirm availability and delivery timing?

Share the reference or specification, quantities and target date. Our team will confirm stock where applicable and the production or delivery plan for your quotation. Custom development and validation can affect the schedule.
