RGY-501 Digital Differential Pressure Gauge Products: RGY-501 digital differential pressure gauge, and the dielectric isolation is a true measurement of corrosive gas and liquid proof digital differential pressure gauge, with high reliability and stability, using ASIC (Application Specific Integrated Circuit) design. Structural design using a miniature silicon pressure sensor (MEMS), the use of stainless steel media isolation. No moving parts to ensure long life. Stainless steel diaphragm pressure is transmitted to the sensor by silicone. Five LCD digital display, eliminates errors due to speculation that the reading is generated. Buttons to adjust the zero position is very simple. Before automatic shutdown, pressure readings can be displayed continuously for 1-15 minutes (optional), to save battery life. Product features: real-time measurement of the speed settings; 11 kinds of pressure unit conversion; low power consumption, longer life; automatic peak record; Accuracy class: 0.05% FS, 0.1% FS, 0.2% FS, 0.4% FS, 0.5% FS, 1.0% FS. Pressure range: Pressure: 0-100kPa - 3.5MPa use environment: temperature: (0 ~ 50) ℃; Relative Humidity: <95%; Atmospheric pressure: (86 ~ 106) kPa; Storage temperature: (- 20 ~ 70) ℃. Display: SFTN LCD, white backlight, five digital display. Power supply: 9V battery powered / 24VDC external power supply / 220VAC external power Description: 4-20mA output, an external 24VDC power supply directly to the digital pressure gauge. Signal output: RS485 communication; 4-20mA; 0-10V Pressure Connection: M20 × 1.5 (can be customized according to user needs); Additional features: Peak Record: record the maximum and minimum values ??occur during pressure measurement; percentages pressure indication: form with the pointer shows the percentage scale pressure measurement values; backlight settings: on-time according to the actual requirements set backlight to reduce power consumption and increase battery life. Quality Assurance: one year product warranty (within the warranty period, such as the use of internal batteries in use, such as the battery runs out, the user can return to the table factory, and only pay the cost of the battery, replace the battery). Accuracy grades identified as a national metrology department in any test failed, the company unconditional refund.
