CSSV1500 Series

The CSSV15000 Series Current Sensors are based on Honeywell’s advanced multisensing scheme, a single power supply, and an integral CAN bus output. They are calibrated and temperature compensated using multipoint temperature characterization. This Honeywell’s patented digital compensation technology enables a high degree of accuracy throughout the sensing range up to ±1500A. The CSSV1500 Series is designed to meet Automotive Safety Integrity Level C (ASIL C) requirements for safety-critical applications. These sensors have two independent sensing and data processing circuits for current sensing. The two processed data are checked for confidence. If they are within the set threshold range, the current data is outputted. If the threshold is exceeded, an alarm message is sent.

Clamp-On Current Sensors

The CO-04-SF and CO-10-SF magnetic field concentrators are designed for nonintrusive and isolated measurements of electric currents. Thanks to the Clamp-On design, the contactless current sensor can be safely installed without interrupting or cutting the cable. Comprised of a soft ferromagnetic shield featuring superior material characteristics such as high linearity and very low hysteresis.

Applications include DC and AC current sensing up to 30 kHz, motor control, battery monitoring, charge control, white goods, and many more. These concentrators were designed to work with and should be paired with a Melexis IMC-Hall® planar magnetic field sensor to create an open loop current measurement system able to measure currents up to ±200 A.

Thanks to its hollow bottom design, the concentrator enables the direct housing of a planar current sensor and its capacitors underneath, thus allowing for a compact and space-saving solution. The concentrator can be directly soldered to the PCB thanks to its four through-hole pins, granting a robust and secure hold.

RF Sensors

CTS’ RF Sensor is a fully integrated diesel particulate filter sensor and control unit, capable of directly measuring soot and ash levels in the particulate filter and controlling after-treatment system operation based on filter measurements.

The diesel particulate filter sensor uses low-power radio frequencies (RF) to transmit and receive RF signals through the filter. Soot and ash accumulation levels, and filter failure symptoms, can be directly measured by the change in response of the RF signal. The sensor provides additional flexibility to engine and after-treatment system designers when attempting to meet increasingly stringent emissions regulations and fuel efficiency standards.


The system is uniquely designed for on-vehicle sensing and control with a wide range of applications including passenger cars, trucks, buses, rail, marine, off-road equipment, and power generation. Originally developed for diesel particulate filter (DPF) applications, the system is equally applicable for gasoline particulate filter (GPF) applications.

System Benefits

Real-time measurements and feedback control based on filter soot and ash levels enable the following benefits for OEM and retrofit applications:

  • Reduced engine fuel consumption through optimized regeneration intervals and duration
  • Advanced filter diagnostics with powerful particulate filter measurement capabilities on the vehicle
  • Decreased warranty claims via more precise feedback control of particulate filter operation
  • Lower maintenance costs by measuring ash directly, cleaning the particulate filter only when needed
  • Extend component life by minimizing high-temperature regenerations
  • Reduce system costs by utilizing smaller or less expensive filters via improved sensing
  • Faster development times by decreasing the resources needed for particulate filter calibration

Specific benefits and system advantages depend upon a number of factors, including baseline application and after-treatment architecture and control strategy.

IPM Series

Honeywell Intelligent Particulate Matter sensor (IPM Series) is a laser-based sensor that detects and measures particle concentration using light scattering for monitoring air quality.

The detection concentration range is 0 mg/m3 to 1,000 mg/m3. A laser light source illuminates a particle as it is pulled through the detection chamber. As particles pass through the laser beam, the light reflects off the particles and is recorded on the photo or light detector. The light is then analyzed and converted to an electrical signal to calculate particle concentration.

During the production calibration process, the sensor records the original laser light intensity parameters and fan speed. The calibration algorithm is applied to the sensor output to minimize sensor drift and improve accuracy over the sensor’s lifetime. This self calibration occurs on each power-on cycle.

BAS Series – Battery Safety Sensors

The BAS Series are automotive-grade aerosol sensors that use the principle of light scattering to detect and report thermal runaway events in lithium-ion battery packs. It detects the presence and concentration of aerosols such as smoke, liquid, and debris that are early indicators of a thermal runaway event in an enclosed lithium-ion battery pack.

The BAS Series measures and reports aerosol concentration from 200 µg/m3 to 10000 µg/m3 using CAN (Controller Area Network) communication protocol. They have a factory-programmed, thermal runaway warning threshold of 5000 µg/m3. These products are designed to meet higher quality and reliability requirements. The BAS series is RoHS compliant.


  • High accuracy and low temperature drift
  • CAN communication protocol
  • Wake-up output and request input for high-reliability system integration
  • Aerosol threshold value of 5000 µg/m3 allows early detection of thermal runaway events

Operating Modes

  • ECO Mode: The sensor operates in ECO Mode when the request pin voltage is set to low. The sensor wakes up for 200 ms and hibernates for the remaining 12000 ms (typical) to reduce power consumption during each measurement cycle of 12200 ms (default value). In ECO Mode, CAN communication is disabled. If the sensor detects an aerosol concentration above the set threshold, a wake-up signal is sent to the BMS (Battery Management System) to initiate a full battery system check.
  • Continuous Mode: The sensor operates in Continuous Mode when the request pin voltage is set to high by the BMS. CAN communication is enabled in Continuous Mode. In Continuous Mode, the sensor monitors and outputs the aerosol concentration to the BMS using CAN communication. The sensor may be switched to ECO Mode by setting the request pin voltage to low.

Value to Customers

  • Early detection of thermal runaway has the potential to mitigate the loss of life and property
  • The ECO mode enables continuous system monitoring in low power mode
  • Thermal runaway detection sensor allows compliance with international regulations and recommendations
  • Solutions may be tailored to exact specifications for improved time to market
  • Lower total system cost and enhanced reliability
