Descripción del producto

CR***7 series hygienic liquid level transmitter is a special instrument customized for the food and pharmaceutical, beverage processing, brewery industry, biological products and other industries. Using standard sanitary stainless steel quick couplings and integrated PTFE probe structure, there is no sanitary dead spots on the whole product and the medium contact parts , which is the ideal product for measuring liquid level in related industries. The whole machine does not have any movable or elastic parts, features are impact resistance, convenient installation, high reliability, high precision and good cost performance. It is the most ideal product for measuring liquid level in related industries. The CR***2 product adds automatic compensation and automatic calibration function, which reduces the maintenance workload of field personnel.

The product complies with GB***6.*****0  and GB***8.*****0 , explosion-proof mark: Ex iaIIC T6 Ga. It has passed the inspection of the National Quality Supervision Center for Explosion-proof Electrical Products and obtained the explosion-proof certificate, number: CNEx*6.***8.

3.Wiring：

The CR***7 series hygienic liquid level transmitter is a standard two-wire or four-wire instrument. The power (signal) terminal is located on the wiring side inside the instrument housing. The signal line should use a shielded wire or a twisted pair of two wires together. Try not to pass through the conduit or the wireway with other power cords, or through high-power equipment.
