1. Installation and Operation Bulletin 101 0 Series Al amp A2 Series Al A2 Installation and Operation Manual The series Al and A2 are microprocessor based digital pressure gauges for positive negative and differential measurement designed to be a direct replacement for mechanical gauges The 2 LCD display gives the gauge improved readability and precision These products also feature 5 user selectable engineering units including in w c mm w c cm w c kPa and Pa The A2 series adds a process arch which gives the gauge a similar look to mechanical gauges by giving a continuous percent output status 1 1 Model Number Configuration A2100 03 ee Housing Display A a a E T a 2 J s d C a E E S E Transmitter oT io ae N Pa I ee ee pt tt 050 ee eee mrs 0 1 2 Specifications Maximum Pressure Ranges lt 4 w c 2 PSI Ranges gt 5 w c 10 PSI Media compatibility Air and compatible non combustible non corrosive gasses Accuracy Axxx0 xx 1 00 Axxx1 xx 0 50 Temperature Ranges Compensated 10 to 140 F 23 to 60 C Operating 10 to 140 F 23 to 60 C Thermal Effect 0 012 FS F Output Signal 4 20 mA option Loop Resistance 750 Q Max for internally sourced power 1800 Q Max for externally sourced power of 36 VDC Power Supply Universal 16 265 VAC or VDC Housing Material Glass Filled Nylon Enclosure Rating Designed to meet NEMA 4X face with opt2. ional cover entire product is weatherproof Electrical Connections screw terminals Response Time lt 100 ms Display 4 Digit red LED 2 digits Process Connection Push on connection for tubing Agency Approvals Pending UL C UL CE Patents Pending Custom calibration including improved accuracy and improved thermal effect are available 1 3 Dimensional Drawings 0 95 2 33 24 1 m 92 1 cat on a NS if E oes W AN on lt p j nR 4 Cc B 2 So f 4 r P W E j j tn r E p i Te Pe Os eo f NN 0O 3 Se Gi a CH P 0 32 a ERN IA A i acca H o 1 l Lhe p n LL 5 11 alt JO HD Q amp a oa i uf f gs j a Bia 2 9 5 33 156 2 73 7 135 4 Flush Mounting For new applications cut a 4 16 hole in the panel Insert the control with the provided gasket through the hole and secure it to the panel with the provided mounting tabs and screws Retrofitting old technology is also easy with the Series Al and A2 They have been designed to fit in industry standard holes ranging from 4 16 to 4 6 so simply remove the old device and insert the new control into the existing cut out Surface Mounting Surface mounting the Series Al or A2 requires the optional weather proof cover Once the control is wired and the weather proof cover has been attached the control can be mounted to any flat surface with the fou
