Meet CraP-es Sensor
Revolution in Crankcase Pressure Feel the Pressure, Prevent the Failure
CraP-es
CraP-es is a wireless & batteryless crankcase pressure sensor that monitors blow-by gas leakage and piston ring wear in real time. Prevent engine damage with autonomous monitoring.
An abnormal increase in crankcase pressure is an early sign of piston ring wear, blow-by gas leakage, and ventilation blockage. CraP-es measures these changes continuously.
Converts the engine's thermal energy into electricity using a Thermoelectric Generator (TEG). Requires no battery changes or external cabling — operates uninterruptedly after installation.
Low crankcase pressure can indicate leaking gaskets, failed components, or excessive oil consumption. CraP-es monitors both high and low pressures.
Connects directly to SCADA, HMI, and ESCOM-es Dashboard systems via BLE and LoRa. Monitor your entire engine fleet from a single screen.
Crankcase Pressure = Silent Danger
Over time, piston rings in engines wear out. Some compression gases leak into the crankcase, a phenomenon called 'blow-by,' which abnormally raises crankcase pressure. Conventional inspections cannot measure this variable instantaneously; issues are usually missed until massive damage occurs.
Real Cost of Reactive Maintenance
Without crankcase pressure tracking, engines degrade silently: oil becomes contaminated, gaskets are strained, and exhaust emissions rise. A damaged piston, broken ring, or oil leak multiplies engine failure costs; unplanned downtime halts production.
Proactive Engine Protection with CraP-es
CraP-es monitors crankcase pressure 24/7 in real time with a 500 ms sampling rate. Any abnormal rise or fall in pressure is detected instantly, allowing operators to intervene before major damage and unplanned downtime occur.
From Blow-By to Ring Wear: One Sensor, Full Visibility
CraP-es measures crankcase pressure directly and with high precision. An upward trend signals blow-by gas leakage and piston ring sticking, while a downward trend indicates gasket leaks and ventilation blockage. Measurements taken every 500 ms are transmitted wirelessly in real time.
TEG Energy Harvesting: Wireless, Batteryless
The sensor generates electricity from the engine's own thermal gradient via a Thermoelectric Generator (TEG). Requiring no battery replacements, cable routing, or scheduled maintenance, CraP-es runs as long as the engine runs.
Scheduled Maintenance with Pressure Curves
Continuous crankcase pressure data shows maintenance teams the actual internal condition of the engine. Significant deviations in the pressure curve allow predicting piston ring life and optimizing maintenance timing. Data-driven planned maintenance replaces unplanned shutdowns.
CraP-es establishes the foundation for plant-wide central engine health management through SCADA and ESCOM-es Dashboard integration. Monitor the crankcase pressure of your entire engine fleet from a single screen, noticing anomalies instantly.
Track Crankcase Pressure Instantly
Continuously monitor crankcase pressure with sampling rates up to 500 ms, detecting piston ring wear and oil leaks before damage occurs.
Frequently Asked Questions
CraP-es (Crankcase Pressure Sensor) is a wireless and batteryless crankcase pressure monitoring sensor developed by ESCOM Enhanced Solutions. It measures crankcase pressure in real time 24/7 in industrial engines, running uninterruptedly without external power or batteries thanks to TEG energy harvesting technology.
Crankcase pressure is one of the most critical indicators of internal engine health. An abnormal pressure rise points to piston ring wear and blow-by gas leakage, while a fall indicates gasket leaks or ventilation blockage. Without continuous monitoring, these issues result in major engine damage and unplanned downtime.
Blow-by is the gas that escapes into the crankcase from the combustion chamber through the clearance between piston rings and the cylinder wall. As rings wear over time, this leakage increases, raising crankcase pressure, contaminating the oil, and rapidly shortening engine life. CraP-es catches this increase early with 500 ms sampling.
CraP-es generates electricity from the engine's thermal gradient via a Thermoelectric Generator (TEG). The temperature difference between the cold and hot surfaces is directly converted into energy. As a result, it requires no battery changes or external power supply; the sensor runs as long as the engine runs.
No. CraP-es can be easily mounted to existing crankcase connection ports. Since it requires no batteries or cables, no significant engine downtime occurs during the installation process. It runs uninterruptedly after a one-time mounting.
Yes. CraP-es supports BLE and LoRa communication protocols. It connects seamlessly to SCADA, HMI, and PLC systems using industrial standards like Modbus and OPC-UA. You can also monitor your entire engine fleet centrally from a single screen via the ESCOM-es Dashboard.
CraP-es can be used on a wide range of engines, including stationary diesel engines, marine engines, large-scale generators, gas engines, and industrial compressors. It provides reliable measurements in extreme environments with an operating temperature range of -40°C to +105°C for the circuit and -40°C to +80°C for the extended pressure sensor probe.
CraP-es is designed for power plants, petrochemical and refinery facilities, shipping and marine systems, the heavy machinery sector, and all kinds of industrial engine operations. It delivers reliable monitoring in any environment where crankcase pressure is critical and unplanned downtime incurs high costs.
