| | | Quartz cylinder pressure sensors must be cleaned at regular intervals depending on the type of application, service period and fuel being used. Any deposits can be removed as specified in the following instructions. Note: The cable must be left connected to the sensor during cleaning or a cap Type 1895... fitted to the sensor connector. 1. Rough cleaning Remove the layer of dirt (consisting of fuel residues, soot and lubricating oil) deposited on the diaphragm with a mild abrasive agent (such as Kistler polishing rubber (grade 240), Type No. 6.970.010). Note: Never clean the front of the sensor with metallic agents (for example, by brushing, grinding, scraping or sand blasting), as this can irreparably damage the diaphragm and hence the sensor. 2. Thorough cleaning We recommend dipping the sensor in a cleaning agent based on a mineral oil (e.g. petroleum ether, petrol), cleaned with a brush and then dried with compressed air. Kistler's 1003 cleaning spray may be used for this task. | | 3. Thorough cleaning in ultrasonic bath If necessary, a thorough cleaning of the sensors can be achieved using an ultrasonic bath, however it is imperative to ensure: • The connecting cable is properly tightened • The sensor is immersed in the cleaning agent up to its seal ring only • The cleaning time does not exceed 2 minutes Note: Cleaning for too long and use of excessively powerful ultrasonic baths can irreparably damage the sensor. | | |
