JKORS Smart TPM Oil Quality Sensor Technical Datasheet Overview

JKORS  Smart TPM Oil Quality Sensor

In industrial frying environments, oil quality monitoring must be precise, repeatable, and validated. A technical datasheet is not simply a marketing document — it defines measurable performance parameters that determine whether a sensor can operate reliably in high-temperature commercial kitchens.

This article provides an overview of the JKORS Smart TPM Oil Quality Sensor technical specification and validation metrics.

Measurement Principle

The JKORS Smart TPM Sensor uses AC impedance-based conductivity measurement and an embedded conversion algorithm to estimate TPM (Total Polar Materials).

As frying oil degrades, polar oxidation by-products increase ionic conductivity within the oil. The sensor applies an AC signal across the electrodes, measures the resulting impedance changes, and converts these variations into real-time TPM percentage values.

Measurement Range:
0.0 – 40.0 %TPM

This range covers the full operational window of commercial frying systems, including the commonly accepted discard threshold of 24–27% TPM.

Accuracy and Precision

The technical datasheet defines multiple performance metrics rather than relying on a single accuracy statement.

  • Measurement Accuracy: ±2% of Full Scale (0–40% TPM range)

  • Precision (Coefficient of Variation): 0.64% – 4.0% (n=10 repeated measurements)

  • Standard Deviation: 0.12 %TPM (n=30)

These values indicate stable repeatability under controlled testing conditions.

Validation Metrics

Performance validation includes statistical comparison against reference analytical methods.

  • Correlation Coefficient (R²): ≥ 0.90 (n=30)

  • Agreement Rate within ±10% tolerance: ≥ 93%

R² demonstrates strong linear correlation with reference measurements, while tolerance agreement provides additional verification within defined error margins.

Temperature Performance

Frying environments demand high thermal resistance and stable measurement performance.

  • Measurement Temperature Range: 20°C – 200°C

  • Storage Temperature: 0°C – 80°C

  • Operating Temperature: 10°C – 60°C

  • Built-in High-Temperature RTD

  • Algorithm-Based Temperature Compensation

The sensor maintains stable performance under continuous exposure to elevated oil temperatures.

Mechanical & Environmental Specifications

Designed for industrial kitchen deployment, the sensor includes:

  • Ceramic substrate with platinum (Pt) etched electrode structure

  • Heat Resistance Rating: ≥ 200°C (sensor tip)

  • Ingress Protection Rating: IP65 

  • Power Supply: DC 24V / 2A

These specifications ensure durability in oil vapor, moisture, and high-heat environments.

Communication & Integration

The JKORS Smart TPM Sensor supports:

  • RS232 / RS485 (standard)

  • Ethernet (standard)

  • BLE (optional)

This allows integration into smart fryers, centralized kitchen control systems, and autonomous robotic cooking platforms.


The JKORS Smart TPM Sensor technical datasheet outlines validated measurement performance, industrial durability, and integration capability suitable for smart frying systems and autonomous kitchen applications.

By defining statistical validation metrics and high-temperature operational limits, the sensor provides a structured foundation for data-driven oil quality management in commercial frying operations.

Collaboration with Food Traceability Services: Key Strategies FryData™ Is Preparing and Future Plans

Image
  Hello, this is the Jkors Robotech FryData™ team. The frying process, the final stage of the food supply chain, has long remained a “black box” in the food industry. While raw materials, processing, logistics, and distribution are increasingly tracked through digital systems, there has been very little real-time data available from the actual cooking stage, such as TPM, temperature profiles, and oil change events. FryData™ is an IoT platform designed to fill this gap for the first time through our SSO-2401 oil degradation sensor and smart fryer solutions. With the recent strengthening of food traceability regulations in Korea and abroad, including FSMA 204 (the U.S. FDA Food Traceability Rule, scheduled for enforcement on July 20, 2028 ), many food traceability platforms are seeking to strengthen transformation-stage data covering processing and cooking operations. In response, FryData™ is actively pursuing partnerships with domestic and global food traceability service prov...

Jkors Robotech's FryData™ service with 10 questions

 The frying industry is a massive global market, yet many processes still rely heavily on experience and intuition. From determining oil replacement timing to managing cooking quality and reducing variations across locations, critical decisions are often made based on human judgment rather than data. With increasing pressure from stricter food safety regulations, ESG requirements, and the need for operational efficiency, the frying process has reached a point where traditional, analog approaches are no longer sufficient. A new approach is required—one that goes beyond simple equipment or measurement and enables full process management through data. FryData™ was created in response to this shift. It is a data platform that collects real-time oil condition and cooking process data, and uses it to optimize operations across stores and production facilities. In this article, we will explore how FryData solves key industry challenges and transforms frying operations through 10 key quest...

ROKINS Unmanned Chicken Robot Store: From “ROKENS” to ROKINS and Smart Frying Oil Monitoring

Image
  The brand of Jkors Robotech’s unmanned chicken robot store is ROKINS . But we recently had a small and rather funny incident during the store design process. Our designer accidentally printed the brand name as “ROKENS” instead of “ROKINS.” Since the store is still under development and construction, these things happen. For now, we are using AI to correct ROKENS → ROKINS before taking the actual store photos. But there is something else in the photo that is worth taking a closer look at. It is the Frying Oil Status Traffic Light at the entrance. Making Frying Oil Status Easy to Understand Frying oil management is an important part of operating a chicken restaurant. In an unmanned environment, relying only on an employee’s experience or visual judgment is not enough. ROKINS is developing a system that monitors frying oil conditions using data and presents the result through a simple traffic-light system. 🟢 Normal 🟡 Good 🔴 Replacement Soon Instead of requiring operators to in...
