Pressure switch use precautions

Pressure switches are widely used in high and low pressure protection control of household, commercial and automotive refrigeration systems, steam conditions and power stations; accumulators, receivers, flash tanks, separators, scrubbers, refineries. It can also be used for high and low pressure protection control of various equipment tools. However, in the selection of pressure switches, the following points must be noted:

1. The necessity of explosion-proof: The explosion-proof form is divided into explosion-proof type and intrinsic safety type, and most of Changye products are explosion-proof type.

2. Do you need to bring instructions: according to customer instructions.

3. Number of contacts: one contact (one output) or two contacts (two outputs).

4. Determination of set value and pressure range: The recommended setting range is between 30% and 65% of the pressure range, and the range can be set between 15% and 90% of the pressure range.

5. The form of the connection difference: adjustable or fixed.

6. Is there a pulsation: If the pressure is pulsating or vibrating, a throttle valve is needed to suppress damage to the meter by the pulsating pressure.

7. Where the diaphragm is used: When measuring corrosiveness, high viscosity or excessive temperature, a diaphragm is required.

PCR Strips

Thin-Walled Polypropylene PCR strip tubes
As one of the largest manufacturers of PCR strip tubes in China for over a decade, we have been supplying PCR 8 strip tubes and PCR single tube to our international customers.
As these PCR tube strips have thin and uniform walls, they can fit in different types of thermal cyclers. As a next step, we are also planning to develop PCR tube strips with attached caps, also called PCR strip tubes with individually attached caps.

What Are PCR strip tubes?
PCR strips tubes allow scientists working with cyclers and enzymes to gain enhanced PCR yield through a faster transmission of heat from block to the reaction. It offers better control over the reaction while speeding up the process with high heating and cooling rates.
