SENTINEL-Plus/Pro Multi-Parameter Humidity Measurement Transmitter - DESCRIPTION
by EdgeTech Instruments

The SENTINEL is available in two versions, the SENTINEL-Plus and the SENTINEL-Pro. Both versions offer the four-measurement parameter capability of the HP125 Humidity Probe. The base probe offers three parameters: RH%, calculated dew point, and temperature. The base HP125 probe may be upgraded to add either absolute pressure or barometric pressure measurements.

SENTINEL-PLUS:

• Calibrated field-replaceable "Smart Sensor Tip" sensor
• Local 2 line LCD Display (up to 4 parameters, rotating between them).
• Two configurable relay alarms (1FORM A)
• (2) configurable 4-20 mA outputs
• (4) configurable 0 to 10 Volt analog outputs
• 24 VDC operation, with universal 120/220 VAC option
• Choice of HP125 Smart Sensor Probe (HPP125 or HPB125)

SENTINEL-PRO (same as PLUS model except in addition):

• (4) configurable 4-20 mA outputs (instead of 2)
• Bluetooth-wireless communication
• USB port
• Data Logging
• Power-on relay (Form-A Contact)

HP125 Probes:

• HPB125:  Barometric Pressure / RH / Temperature / Calculated Dew Point
• HPP125:  Pressure / RH / Temperature / Calculated Dew Point

• Relative Humidity ±1.8% @ 23°C (0 TO 90% RH)
• Temperature:  ±0.5°C
• Dew Point:  ±1°C for –10°C to 95°C DP and + 2°C for –60°C to –10°C
• Pressure:  ±1 mbar @ 25°C (600 to 1200 mbar) / ±5mbar (-40°C to +125°C)
