Model PI Intrinsically Safe Pressure Gauge DESCRIPTION As an in-process gauge or portable calibrator, the hand-held Intrinsically safe systems limit the thermal and electrical energy Model PI delivers long-lasting, enhanced accuracy perfor- to the hazardous area to help prevent ignition. mance. Accuracy of 0.2 % coupled with an enhanced resolution, Division 1: present or likely to be present in normal operation 4½-digit display makes this unit an excellent transfer standard for calibrating pressure measuring equipment. The PI is rugged and features high/low pressure capture with a field-adjustable update rate from three-to-ten times per second. These units are manufactured from stainless steel and use sensor technology which has no moving parts, requires little recalibration and has excellent overpressure tolerance. NEMA 4 rating provides EMI and RFI protection. Units of measure are fieldselectable and the unit is offered with gage, absolute, vacuum, or compound reference. The Model PIW is powered by one or two common 9 V alkaline batteries. FEATURES • High accuracy: 0.2 % full scale • Ranges to 10000 psi - gage, absolute, vacuum, or compound • Stainless steel construction • On/off switch • CE compliant • 9 V battery power • Optional pressure ports • Optional carrying case and panel mounting ring • High/low capture and store • 4½-digit display with 0.5 in height Division 2: not present in normal operation Group A: Acetylene Group B: Hydrogen Group C: Acetaldehyde, Ethylene, Methyl Ether Group D: Acetone, Gasoline, Methanol, Propane Group E: Metal dust Group F: Carbon dust Group G: Grain dust Model PI PERFORMANCE SPECIFICATIONS Characteristic Measure Accuracy 0.2 % of full scale BSFL Pressure range, 0 psi to: ADDITIONAL SPECIFICATIONS Pressure range (psi) Incremental display steps 15, 50, 100, 200, 500, 750, 1000, 1500, 2000, 5000, 7500, 10000 psi Maximum safe over pressure (psi)1 0 psi to 15 psi = 15 75 0.01 0 psi to 50 psi = 50 250 0.05 High and low capture Standard 0 psi to 100 psi = 100 500 0.1 Update speed 3 per sec 0 psi to 200 psi = 200 1000 0.1 0 psi to 500 psi = 500 1500 0.5 0 psi to 750 psi = 750 1500 0.5 0 psi to 1000 psi = 1K 2000 1 ENVIRONMENTAL SPECIFICATIONS Characteristic Measure 0 psi to 1500 psi = 1.5K 3000 1 Temperature, operating (standard) -18 °C to 82 °C [0 °F to 180 °F] 0 psi to 2000 psi = 2K 4000 1 0 psi to 5000 psi = 5K 7500 5 0 psi to 7500 psi = 7.5K 12000 5 0 psi to 10000 psi = 10K 15000 5 ELECTRICAL SPECIFICATIONS Characteristic Measure Rating NEMA 4 Power, Model PIW One or two 9 V alkaline batteries (included) Power, Model PIV 11 Vdc to 32 Vdc @ 100 mA (3 ft cable included) 1 Maximum safe overpressure is the pressure which the unit can experience occasionally without the loss of accuracy or permanent damage MOUNTING DIMENSIONS AND CHARACTERISTICS MECHANICAL SPECIFICATIONS Characteristic Measure Diameter 93,98 mm [3.7 in] Display 4 LCD digits - 12,7 mm [0.5 in] high Pressure port 9/16-18 UNF-2B - female straight thread with SAE spec J514 o-ring boss Wetted parts Stainless steel Case material Stainless steel Low battery indication Standard Face membrane Tactile feedback raised buttons Calibration data Stored on memory chip For reference only 2 Honeywell • Sensing and Control Model PI Intrinsically Safe Pressure Gauge ORDER CODE Notes PI Z W 200 G * = Example SERIES PI POWER W = Battery powered (9 v alkaline)* PRESSURE RANGE (psi) 15 = 0-15 50 = 0-50 100 = 0-100 200 = 0-200* 500 = 750 = 1K = 1.5K = 0-500 0-750 0-1000 0-1500 2K = 5K = 7.5K = 10K = 0-2000 0-5000 0-7500 0-10000 REFERENCE G A V C = = = = Gage (std) reads zero at atmosphere * Absolute (opt) reads zero at vacuum (15 psi or higher) Vacuum (opt) scaled in In Hg (15 psi or lower) Compound (opt) reads both positive & negative (vacuum) pressure ELECTRICAL CONNECTION Z = No electrical connection (Model PIW - 9 V battery)* Call factory for availability of other electrical connections and cable lengths.
