PT100 RTD Applications Across San Salvador & Central America
How precision thermal instrumentation drives productivity in the greater San Salvador metropolitan area, from Ilopango to Soyapango industrial corridors.
Food, Beverage & Sugar Refining
In the fertile agricultural processing belts surrounding San Salvador, high-accuracy temperature loops are vital for sugar batch crystallizers, fermentation vats, and automated pasteurization lines. Our Class A thin-film PT100 elements, protected in seamless 316L stainless steel sheaths, resist severe washdown chemicals while preventing thermal drift.
Pharmaceuticals & Cleanroom Synthetics
San Salvador acts as a central pharmaceutical logistics and fabrication hub for Central America. Our 3-wire and 4-wire PT100 probes deliver 0.03°C repeatability inside autoclaves, stability chambers, and cleanrooms, ensuring full compliance with stringent GMP regulations, FDA validation guidelines, and ISO 17025 verification protocols.
Geothermal & Thermal Energy Generation
Leveraging El Salvador’s volcanic geothermal energy infrastructure (such as plants near Ahuachapán and Berlín), our mineral-insulated (MI) PT100 cable assemblies withstand intense vibration, corrosive volcanic sulfur traces, and constant thermal pressure cycles ranging reliably from -200°C up to +600°C.
Plastics Extrusion & Packaging
Converters and packaging plants located in the Plan de La Laguna industrial park rely on high-response bayonet and screw-in PT100 sensors. Uniform thermal profiling within multi-zone barrel heating jackets eliminates polymer degradation and reduces structural wall variations during blister formation and stretch film extrusion.
Textile Dyeing & Maquila Finishing
Industrial garment exporters in the Free Trade Zones require precise atmospheric immersion sensors. Our Teflon (PTFE) and PFA-jacketed sensor lines shield the sensitive platinum resistors from acidic dyes, caustic alkaline baths, and pressurized fabric curing steamers, safeguarding uninterrupted uptime.
Cold Chain & Logistics Hubs
San Salvador's central geographical position requires real-time temperature data across refrigerated warehouses and reefer container terminals. Integrated with our RTD-to-digital signal conversion boards, these probes feed telemetry networks to safeguard perishables without thermal logging dropouts.
Industrial Modernization & Sensor Trends in El Salvador
Macro factors shifting procurement strategies for instrumentation, SCADA integrations, and factory automation in Central America.
1. Nearshoring & Modernization
As international supply chains reorganize closer to North American consumer bases, manufacturing facilities throughout El Salvador are retrofitting legacy machinery with automated PLC loops. Precision PT100 RTDs replace old mechanical dials, delivering digital transparency directly to modern ERP platforms.
2. Transition to IO-Link & 4-20mA HART
Industrial managers across San Salvador are converting raw resistance measurements into noise-immune 4-20mA current loops and IO-Link protocols. We supply RTD probes fitted with custom miniature PCB head transmitters designed to fit inside explosion-proof terminal enclosures.
3. Renewable Energy Integration
With El Salvador leading in renewable energy investments—spanning geothermal, solar arrays, and hydroelectric projects—robust temperature sensing is critical for cooling transformers, sub-station switchgears, and battery energy storage containers (BESS).

Our End-to-End Quality Architecture
Every sensor and PCBA module undergoes systematic functional testing, thermal aging, and optical verification before export packaging.
Stage 01
Gerber & Engineering DFM
Our engineers perform Design For Manufacturability (DFM) reviews on PCB trace layouts, probe sheath mechanical tolerances, and thermal response profiles prior to tooling.
Stage 02
BOM Procurement
Platinum thin-film chips, ceramic cores, 316L sheaths, and electronic components are acquired directly through verified supply links with full certificate transparency.
Stage 03
SMT Assembly & Swaging
Automated Yamaha surface-mount placement for transmitter boards, coupled with hydraulic high-pressure swaging machines to seal RTD probes to IP67/IP68 standards.
Stage 04
Calibrated Thermal QC
Probes undergo ice-point (0°C) testing, oil-bath dynamic sweep verification, and insulation resistance checks at 500V DC to ensure zero leakage before dispatch.
Frequently Asked Questions: Sourcing PT100 Sensors in San Salvador
What is the difference between 2-wire, 3-wire, and 4-wire PT100 RTDs for factory setups?
A 2-wire configuration is suited for very short runs because lead resistance adds directly to the platinum sensor measurement, generating temperature errors. A 3-wire system is the standard in San Salvador's processing plants, using a third wire to calculate and compensate for lead wire resistance in the control bridge. A 4-wire circuit offers the highest accuracy, completely eliminating cable length resistance effects; it is essential for pharmaceutical cleanrooms and laboratory calibrations.
Can Mivo Electronics customize probe dimensions, thread pitches, and cable materials?
Yes. As a direct manufacturer, we fabricate probes to exact technical specifications. We offer outer sheath diameters from 2.0mm to 12.0mm, insertion lengths from 20mm to over 2000mm, process connection threads (1/4 NPT, 1/2 NPT, G1/2, M10), and specialized lead insulations including Teflon, Silicone, Glass-fiber braid, and armored stainless steel overbraids.
How are shipments handled to San Salvador and customs clearance managed?
We ship directly to Monseñor Óscar Arnulfo Romero International Airport (SAL) via expedited air freight (DHL, FedEx, UPS) with transit times typically ranging between 4 to 7 working days. For consolidated orders, ocean transport can be routed to the Port of Acajutla. We provide complete commercial documentation, including certificates of origin, accurate HS codes (typically 9025.90 for sensor parts), and packing declarations to ensure smooth clearance through El Salvador customs (DGA).
What is the minimum order quantity (MOQ) for custom sensor builds?
Our production lines accommodate small engineering batches and high-volume industrial rollouts. Custom PT100 RTD sensor probes start with a flexible MOQ of just 10 pieces. Turnkey PCB assembly services begin at 5 pieces for prototyping, enabling design validation before volume production.
