316 Stainless Steel Capacitive Level Sensor with IP67 Protection and HART Communication for Harsh Environments

Product Description:

The KCF600 series capacitive level transmitter is designed to continuously detect a variety of liquids in harsh conditions such as high temperature and pressure, high corrosion, easy crystallization, and easy plugging. It is suitable for measuring water, acid and alkali solutions, and the water level in the boiler.

This level transmitter has no movable or flexible parts, making it highly reliable and resistant to impact. Its installation is easy, and it offers high precision at a reasonable cost. In various situations, it is capable of replacing traditional float type, input type, and differential pressure type of level transmitters.

The key parts of the KCF600 level transmitter utilize advanced RF capacitive sensing circuits that are precisely compensated by temperature and corrected for linearity. This ensures that the output is a standardized electrical signal (typically 4~20mA). To configure the system, you can choose from the HART, CANBUS, and 485 communication protocols.

The transmitter has a self-calibration feature that covers the full range, enabling users to perform "zero" and "range" automatic calibrations using two keys. This feature allows for easy adaptation to diverse and complex situations.

Installation and commissioning

The cable and rod level transmitter has a variety of fixed ways to adapt to different site conditions. When the site cannot provide the process facilities such as the M20 × 1.5 female thread or flange, you can choose three methods of installation (wall-mounted, horizontal pipe rack and vertical tube rack, which make you handy in the on-site installation.(With pictures)

When measuring the media of the larger mobility, the user can choose the weight attachment in order to prevent the sensor form violent swing, which can play the role of the stability of the sensor. The heavy objects must be put into the bottom of the container when adding weight, so as not to break the sensor’s wire.

When the site conditions are bad, the user should use the sensor shield to protect the sensor in order to avoid foreign body damage or affect the measurement accuracy.

If the containers are not metal, we need to put the transmitter enclosure with a wire access to the bottom of the container when using a KCF600 rod level transmitter; otherwise the measurement is not accurate.

This product has been calibrated at the factory; he need for field adjustment may take the following methods:

A: Intelligent circuit debugging method:

Site-zero----- When the liquid level is located in the lowest place, holding down the "Z" key and "S" key for 8 seconds after the same time release, and then "Z" key click, the output current is automatically adjusted to 4mA.

Site - filled ------ When the liquid level at the highest place, holding down the "Z" key and "S" key for 8 seconds after the same time release, and then "S" key click ,the output current is automatically adjusted to 20mA.

B: Analog circuit debugging method:

When the liquid level in the next limit, use the screwdriver slowly rotating "Z" potentiometer, observe the ammeter readings close to 4mA

When the liquid level in the upper limit, use the screwdriver slowly rotating "S" potentiometer and observe the ammeter readings close to 20mA

And operate it for 2-3 times more, until the zero and span were accurate 4mA and 20mA. After adjustment, tighten the cover of the transmitter should be.

Note:

1. Products supply with product certification and manual, which have product number, technical parameters, wiring diagram, and the date of manufacture, please check to avoid the mistake.
2. The installation should be based on the product connection and thread types, check the site interface is consistent with the product interface or not.

7. Transportation, storage should be to restore the original packaging and stored in a cool, dry, ventilated warehouse.
8. The installation process should pay attention to avoid the breaking of the skin of the sensor wire.
9. When installing the sensor wire, the distance from pool wall should be at least 10CM above, otherwise the measurement would be not accurate.
10. The grounding line of the whole PTFE structure and the rod level must be conduct with measured media; otherwise the measurement would be not accurate.
11. The installation site should take effective lightning protection measures.
12. The enclosures of any transmitter in this series must be grounded; grounding resistance should be less than 4Ω.
