Pressure controller Selection considerations:
??? Pressure controller It has been widely used in commercial, * * *, oxygen cabin, automotive refrigeration system, compressor, petrochemical and other industries. Factory * * * should pay attention to the following points when choosing the pressure switch.
1. do you need on-site instructions? 2. consider whether the medium needs explosion-proof. Explosion proof pressure controller Divided into flameproof and intrinsically safe, most of them are flameproof.
3. electrical contact points, one output point or two contacts two outputs.
4. the setting range of the setting value and the pressure range is between 30% and 65% of the pressure range, and can be set between 15% and 90% of the pressure range.
5. the form of connecting difference is adjustable or fixed.
6. if there is a pulsation, if the pressure is fluctuating or vibrating, the throttle valve should be provided to suppress the damage of the fluctuating pressure team.
7. with diaphragm to install and debug the instrument, simplify installation and commissioning process, such as line and zero, and reduce installation and commissioning cost.
The mechanical pressure controller can set the action value according to different requirements. When the pressure reaches this value, the switch sends out action. Note that the mechanical pressure switch needs to be set up in our workshop, and the intelligent pressure switch can be set by the user.
