GUEMISA is an official distributor, offering technical advice to help you choose the exact model. This advice is free and included with the purchase of the equipment. Before recommending a sensor, we analyze what needs to be measured, under what conditions, and how the signal will be used. We also help troubleshoot problems with existing equipment and replace discontinued models.

How can we help you?

• Choose the model and order reference: Range, accuracy, resolution, output signal, power supply, connection, and mounting. Many brands are configured with a multi-digit order code; we provide the complete code.
• Equivalencies: Find the equipment that replaces a discontinued or another brand with the same assembly and the same signal.
• Integration: adapt the signal to the PLC or acquisition system (4-20 mA, 0-10 V, pulses, RS 485, fieldbuses) with converters and isolators when necessary.
• Problem solving: unstable readings, out-of-range signal, noise, or failures after changing equipment.
• Certificates: Which certificate to request (manufacturer's, ENAC calibration, or DAkkS). More at Calibration and certificates.
• Customized equipment: if there is no standard one that will work, Custom OEM manufacturing.

What data should you send us?

• The variable to be measured and the range.
• The necessary precision.
• The power supply and the output signal that the system expects.
• Environmental conditions and assembly limitations.
• If it is a replacement: the reference of the current equipment, its technical data sheet and, if possible, a photo of the label.

Tools for finding a reference

• Order reference index of the brands we distribute.
• Technical guides to choose sensor according to the application.
• Our brands.
