Descripción detallada
This version of the HMP45C has a connector instead of pigtails for connecting the sensor to a MetData1 Weather Station or CS110 Electric Field Meter. The probe uses a HUMICAP capacitive polymer H chip to measure relative humidity, and a PRT to measure temperature. Relative humidity range is 0 to 100% RH, and temperature range is -40° to +60°C. A solar radiation shield is required if the probe will be exposed to sunlight.
Especificaciones
- Supply Voltage: 12 Vdc nominal (typically powered by datalogger)
- Current Consumption: ≤4 mA (active)
Relative Humidity
- Sensor: Vaisala’s HUMICAP® H-chip
- Measurement Range: 0.8% to 100% RH, non-condensing
- Output Signal Range: 0.008 to 1 Vdc
- Accuracy at 20°C:
- Against Factory Reference: ±1% RH
- Field-Calibrated Against References: ±2% (0% to 90% range);
±3% (90% to 100% range)
- Temperature Dependence: ±0.05% RH/°C
- Long-Term Stability: Typically, better than 1% RH per year
- Response Time: 15 seconds with membrane filter (at 20°C, 90% response)
- Settling Time: 500 milliseconds
Temperature
- Temperature Sensor: 1000 ohm Platinum Resistance Thermometer
- Measurement Range: -39.2° to +60°C
- Output Signal Range: 0.008 to 1.0 V
- Accuracy: see graph in HMP45C product brochure
Compatibilidad
The connector can be attached to the CS110 Electric Field Meter or MetData1 Weather Station. The CS110 has a CR1000 and the MetData1 has an on-board CR10X.
Mounting
The HMP45C-LC should be housed in a 41003-5 10-plate naturally-aspirated solar radiation shield. This radiation shield mounts to a tripod or tower mast, crossarm, or user-supplied pole.
