1 / 2 page ![]() GREYSTONE HAS AN ISO 9001 REGISTERED QUALITY SYSTEM OUTSIDE HUMIDITY/TEMPERATURE TRANSMITTER HTOB SERIES PRODUCT DESCRIPTION The HTOB series uses a highly accurate and reliable Thermoset Polymer based capacitance humidity sensor and Platinum RTD temperature sensor together with state-of-the-art digital linearization and temperature compensated circuitry to monitor humidity levels. A hinged, gasketed weatherproof Polycarbonate enclosure provides easy of installation and protection from the elements. TYPICAL INSTALLATION For complete installation and wiring details, please refer to the product installation instructions. The HTOB should be mounted on an outside North facing wall, under the eaves which will provide protection from direct sunlight and wind. The HTOB can be mounted directly to buildings wall face using the four provided mounting holes. There is a 0.85” hole for conduit connection on rear of enclosure. HUMIDITY SENSOR TYPE Thermoset polymer based capacitive TEMPERATURE SENSOR TYPE 1000Ω Platinum, IEC 751, 385 Alpha, thin film HUMIDITY SENSOR ACCURACY ±2, 3, or 5 %RH (5 to 95 %RH) TEMPERATURE SENSOR ACCURACY ±0.1% of span SENSOR RESPONSE TIME 15 seconds typical MEASUREMENT RANGE 0 to 100 %RH HYSTERESIS ±1.5 %RH maximum REPEATABILITY ±0.5 %RH typical LINEARITY ±0.5 %RH typical OPERATING TEMPERATURE -40 to 50°C (-40 to 122°F) OPERATING HUMIDITY 0 to 95 %RH non-condensing POWER SUPPLY 18 to 35 Vdc, 15 to 26 Vac CONSUMPTION 22 mA maximum INPUT VOLTAGE EFFECT Negligible over specified operating range PROTECTION CIRCUITRY Reverse voltage protected and output limited OUTPUT SIGNAL 4-20 mA current loop, 0-5 Vdc or 0-10 Vdc (factory configured) OUTPUT DRIVE @ 24 VDC Current: 550Ω max Voltage: 10,000Ω min INTERNAL ADJUSTMENTS Clearly marked ZERO and SPAN pots ENCLOSURE B: Grey Polycarbonate, UL94-V0, IP65 (NEMA 4X) 117mm W x 102mm H x 53mm D (4.6” x 4.0” x 2.1”) TERMINATION Screw terminal block (14 to 22 AWG) COUNTRY OF ORIGIN Canada SPECIFICATIONS OSA Humidity Sensor North 116.5 mm 4.585" 0.5" NPT 53.7 mm 2.115" 92 mm 3.62" 38mm 1.5" 112.5 mm 4.43" 99.7 mm 3.925" 132 mm 5.19" 139.7 mm 5.5" |
