3. Поставување и инсталација
3.1. Безбедносни мерки на претпазливост
- Ensure the power supply to the system is disconnected before installation to prevent electrical shock.
- Носете соодветна лична заштитна опрема (ЛЗО), како што се ракавици и заштита за очи.
- Verify that the sensor's specifications match the system requirements before installation.
- Avoid overtightening the sensor during installation to prevent damage to the thread or sensor body.
3.2. Чекори за инсталација
- Подгответе го местото за монтирање: Identify a suitable port on the engine or system for the oil pressure sensor. Ensure the port has an NPT1/8 thread.
- Нанесете средство за заптивање на конец: Apply a suitable thread sealant (e.g., PTFE tape or liquid sealant) to the NPT1/8 thread of the sensor to ensure a leak-free seal.
- Инсталирајте го сензорот: Carefully thread the sensor into the prepared port. Hand-tighten first, then use a wrench to tighten it securely, but do not overtighten.
- Поврзете ги електричните инсталации:
- Connect the positive power supply (6-24V) to the appropriate terminal.
- Connect the output signal wire (10-184Ω) to your gauge or monitoring system.
- Connect the alarm wire (0.8Bar) to your alarm indicator or system.
- Осигурајте се дека сите врски се сигурни и правилно изолирани.
- Потврдете ја инсталацијата: After installation, visually inspect all connections for tightness and proper wiring.

4. Упатства за работа
4.1. Основно работење
Once properly installed and wired, the KUS KE21104 sensor will continuously monitor the oil pressure within its measuring range of 0 to 5 Bar. The sensor operates automatically when the system is powered on.
4.2. Reading Output and Alarm Function
- Pressure Reading: The sensor provides a standard resistance output signal ranging from 10 to 184 Ω, which corresponds to the 0-5 Bar pressure range. This signal is typically fed to a compatible oil pressure gauge or monitoring system for display.
- Функција за аларм: The sensor is equipped with an alarm contact that activates when the oil pressure drops to 0.8 Bar or below. This alarm signal can be connected to an indicator light or audible alarm to alert the operator of low oil pressure conditions.
5. Одржување
5.1. General Care and Inspection
- Periodically inspect the sensor and its connections for any signs of damage, corrosion, or leaks.
- Ensure electrical connections remain clean and secure.
- Clean the exterior of the sensor with a soft, dry cloth if necessary. Avoid using harsh chemicals or abrasive materials.
5.2. Складирање
If the sensor needs to be stored, ensure it is kept in a clean, dry environment, away from extreme temperatures and direct sunlight. Protect the threaded portion and electrical terminals from physical damage.
