SpecificationsRange: 0kPa~10kPa…40MPa Overpressure: 1.5FS Pressure Type: Gauge, Absolute or Sealed Gauge Accuracy: ±0.5%FS Power Supply: 11V~28V DC Output: 4mA~20mA DC (2-wire) Load Resistance: ≤ (U-11) / 0.02(Ω) Zero Thermal Drift: ±0.02%FS/ºC FS Thermal Drift: ±0.02%FS/ºC | Long-term Stability: ±0.3%FS/year Operation Temperature: -25ºC~75ºC Storage Temperature: -40ºC~80ºC Relative Humidity: 0%~85% O-ring: Viton Diaphragm: SS316L Leading Wire: silicone rubber Gross Weight: 22g Media Compatibility: liquid or gas compatible with stainless steel and viton |
Button Function 1. Without pressure, press the button for 5s for zero clearing, it outputs 4mA DC.
2. If the transmitter is excited while pressing the button, it enters calibration mode, the output can be calibrated by LED indication. Please see below chart for functions.Button Operation | Phenomenon | Function |
Excite power supply after pressing button | LED light on | Enter calibration mode |
Pressurize to lower limit of pressure | LED flash 2 times | Zero calibration finished, low current calibration finished |
Pressurize to upper limit of pressure | LED flash 3 times | FS calibration finished, middle current calibration finished |
Pressurize to upper limit of pressure | LED flash 4 times | Calibration coefficient storage finished, high current calibration finished |
