What are the Types of VDO Oil Pressure Senders?
VDO offers a variety of oil pressure senders tailored to different applications, each with distinct specifications and features.
- Maximum Pressure Ratings:
- 80 PSI / 5 Bar: These senders are suitable for lower-pressure applications and are commonly used in various automotive and industrial settings.
-
150 PSI / 10 Bar: These senders are designed for higher-pressure applications and are often used in more demanding environments.
-
Thread Types:
- 1/8″ – 27 NPTF: This is a common thread type used in many VDO oil pressure senders, ensuring compatibility with a wide range of installations.
- 1/4″ – 18 NPT: Another thread type available, particularly useful for specific applications requiring this thread size.
-
M10 x 1.0 and M12 x 1.5: These metric threads are used in certain models, catering to different installation requirements.
-
Resistance Range:
-
The typical resistance range for VDO oil pressure senders is 10Ω to 180Ω, which is consistent across various models. This range ensures compatibility with VDO gauges and other measurement instruments.
-
Operating Voltage:
-
VDO oil pressure senders operate within a voltage range of 6V to 24V DC, making them versatile for use in different electrical systems.
-
Grounding:
-
Most VDO senders have a standard ground (sender case to common ground), and they do not require the use of Teflon tape or pipe sealant to avoid interfering with grounding.
-
Operating Temperature:
- The operating temperature range for VDO oil pressure senders is typically from -25°C to +100°C, ensuring reliable performance across a wide range of environmental conditions.
What are the Warning Contacts in VDO Oil Pressure Senders?
- Senders with Warning Contacts:
- These senders include a warning contact point that can trigger warning lights or alarms when the pressure falls below a specified threshold. For example, some models have a warning contact point at 7 PSI or 8.5 PSI.
-
Advantages: These senders provide an additional layer of safety by alerting the user to potentially critical pressure drops, which can be crucial in applications where maintaining optimal pressure is vital.
-
Senders without Warning Contacts:
- These senders do not include a warning contact and are used in applications where such alerts are not necessary.
- Advantages: They are simpler in design and may be more cost-effective. They are suitable for applications where continuous monitoring is sufficient, and alerts are not required.
