A little of history
GUILCOR key dates

1987 Creation of Guilcor

JACQUES GUILLON
Founder of GUILCOR

1997 Development of the range of PT100, Pt1000, KTY and thermocouple probes

Jacques GUILLON (Son)
He joined the company in 1997 and was at the origin of the diversification of the group's product range.

2013 ISO9001 certified

2017

Elrick GUILLON (Grandson)
Joined the company in 2017 as a sales representative. He is also in charge of boosting communication.

2023 Passage of ISO14001

The history of the GUILCOR group begins in 1987 when Jacques GUILLON, after having been a salesman in the company LEROY SOMER, decides to create a company which would supply PTC thermistor probes to improve the thermal protection on the range of electric motors. His former employer will be his first client, the idea works and the GUILCOR company is born.

10 years later, it was his son Jacques GUILLON, second of the name, who in turn showed an aptitude for capturing the spirit of the times when he decided to diversify the range of temperature sensors to offer PT100, Pt1000, KTY probes. and thermocouple. From this date, GUILCOR expanded its customer base, and continued to expand its product range by integrating NTC thermistor probes in 2003 that can be adapted to new areas of application. This is how GUILCOR will become over time a benchmark in the design, manufacturing, and distribution of sensors. Today, the group maintains strong momentum and aims to exceed one million probes sold per year.

Our processes

The key elements

ISO 9001 and soon ISO 14001

150 000 sensors and thermometers in stock

3 to 5 weeks of production time

Custom sensor manufacturing process

Definition of the need with the client

Depending on the knowledge of your needs, we bring our expertise to determine with you the type of sensor that will be the most suitable: the shape, the utility, the certifications, the mechanical and dimensional constraints, etc.

Technical proposition

Once your need has been clearly identified, we provide you with technical drawings in 2 or 3D and all documentation of the technical characteristics of the proposed product.

Establishment of costing and estimation of production deadlines

From these elements we quantify the prototypes, the series and the tools and machines if necessary and determine the production times.

Provision of prototypes

We agree ? Perfect, we then provide you with prototypes for the dimensional and functional validation of our products in the laboratory as well as the validation of certificates or associated documentation.

Pre-series test

Before launching into production, the pre-series are installed on your equipment to verify that there are no more technical modifications to be made.

Launch of the actual production and delivery of the products within the negotiated deadlines

Our quality standards

Today ISO 9001 since 2013

Tomorrow ISO 9001
