Southern Human Services Center Smith Sinnett /2020072 <br />HVAC and Roof Renovations Orange County,North Carolina <br />BAS Sensors and Transmitters 23 09 13.23 - <br /> 3 <br />h.Optional LCD display-SP and RH100A series <br />i.Optional set point adjustment-SP series <br />j.Optional push button override-RH100A series <br />L.Relative Humidity Sensor –Duct Mounted <br />1.Provide duct mounted relative humidity sensors as indicated within the Field termination <br />schedules and/or control diagrams. Duct mounted relative humidity sensors shall meet,at <br />minimum,the following requirements: <br />a.ABS housing with conduit entrance. <br />b.Sensor to be laser trimmed thermoset polymer based capacitive type. <br />c.24 Vac/dc power supply. <br />d.4-20 mA two wires,0-10 Vdc and/or 0-5 Vdc output proportional to relative humidity <br />range of 0%to 100%and compatible with BMS. <br />e.2%accurate (5-95%RH).(3 &5 %accurate units available) <br />f.230mm (9”)probe length. <br />g.Operating temperature range of 32°F to 158°F. <br />h.Reverse voltage protected and output limited. <br />i.60 micron HDPE filter <br />M.Combination Relative Humidity And Temperature Sensors <br />1.Where there is a requirement for the monitoring of both relative humidity and temperature at <br />the same location,the BMS Contractor shall provide a combination relative humidity sensor <br />and temperature sensor. The individual sensors must each meet the specifications details <br />above. <br />N.Static Pressure Sensor –Duct Mounted <br />1.Provide duct mounted static pressure sensors as indicated within the Field termination <br />schedules and/or control diagrams. Static pressure sensors shall meet,at minimum,the <br />following requirements: <br />a.Input range shall be appropriate for the application. Select range such that it covers <br />from zero duct static pressure relative to the exterior of the duct up to a static pressure of <br />between 20%and 50%in excess of the maximum static pressure that could be <br />encountered in the duct relative to the duct exterior. Typically,for low pressure <br />commercial duct consider using a range of 0 to 2”wc.,for medium pressure duct use a <br />range of 0 to 6”wc.and for high-pressure duct use a range of 0 to 10”wc. <br />b.4-20mA,0-5 or 0-10Vdc output proportional to pressure input range compatible with <br />BMS system. <br />c.1%Full scale output accuracy <br />d.Operating temperature range of 32°F to 140°F. <br />e.Easily accessible,integral non-interacting zero adjustment. <br />f.Minimum over pressure input protection of two times rated input or 20 psi whichever is <br />greater. <br />O.Room Pressure Sensor <br />1.Provide space static pressure sensors as indicated within the Field termination schedules <br />and/or control diagrams. Static pressure sensors shall meet,at minimum,the following <br />requirements: <br />a.Input range of -0.2”to +0.2”wc. <br />b.4-20mA,0-5 or 0-10Vdc output proportional to pressure input range compatible with <br />BMS system. <br />c.1%accuracy of range <br />d.Operating temperature range of 0°C to 60°C. <br />e.Operating temperature range of 32°F to 140°F. <br />f.Easily accessible,integral non-interacting zero adjustment. <br />g.Minimum over pressure input protection of two times rated input or 20 psi whichever is <br />greater. <br />P.Differential Pressure Sensor –Air (Filter/Coil Monitoring) <br />DocuSign Envelope ID: 94E7997D-4F29-42F6-A9B4-0A160438D2A6
