BPK104 intelligent pressure controller

BPK104 intelligent pressure controller I. Introduction BPK104 series of intelligent pressure controller is a pressure measurement, display, output, control in one of the pressure measurement and control products. The product is fully electronic structure, front-end separation membrane oil-filled core, the high-precision A / D converter, the microprocessor operation processing, live shows, and output one analog and two-way switch. The smart pressure controller uses a flexible, easy to operate, easy to debug, safe and reliable. Widely used in water and electricity, water, petroleum, chemical, mechanical, hydraulic and other industries, the pressure of the fluid medium on-site measurement, display and control. Second, the technical performance measuring range -100 ... 0 ~ 35 ... 100 (KPa) Display 0.56 "; digital pipe 0 ~ 2,20,35 ...... 100 (MPa) display range -1999 to 9999 Overload pressure ≤ 200% FS Media temperature - 20 ~ + 85 ℃ Measuring media compatible with 316L stainless steel variety of gases, liquids ambient temperature - 20 ~ + 70 ℃ supply voltage 24VDC (BPK104) Relative humidity 0 to 80% output signal 4 ~ 20mA standard signal output (optional ) two control relay output 220VAC 3A ≤1ms response time sampling rate of 4 times / second Accuracy ± 0.3% FS ± 0.5% FS Pressure connection external thread M20 × 1.5 or user-defined long-term stability ≤ ± 0.2% FS / Year Electrical interface terminals product features ● 100 standard instrumentation installation ● two control points set the scene ● 4 ~ 20mA standard signal output (optional) ● Two relay outputs to control 220VAC 3A ● 4-digit LED display, ignore Error Fourth, the installation 4.1 Mechanical installation: BPK104 by pressure fittings (M20 * 1.5) (other sizes available when ordering joints), directly mounted on the hydraulic piping in critical applications (such as severe vibration or shock). pressure fittings can be performed by micro-mechanical decoupling hose Shin Min Control NOTE: Range must be mounted vertically less than 100KPa 4.2 Electrical connection: In order to prevent electromagnetic interference should note the following:? line connections using shielded cable as short as possible? ? Try to avoid direct access to user devices cause interference or electrical wiring and electronic devices? If the installation using a micro hose, the housing must be grounded separately
