East Hills Instruments

Specifications include all effects of linearity, hysteresis, repeatability, temperature, and stability for one year. Accuracy 0 to Full Scale: ±(0.05% of Reading + Floor Term*) *Floor Term = 0.005% of FS or display resolution, whichever is greater. Vacuum: ±(0.25% of Reading + Vacuum Floor Term*) * Vacuum Floor Term (VFT): For 16 and 36 PSI, VFT = 0.004 PSI For 300 PSI, VFT = 0.01 PSI For 1 or 2 bar, and 100 or 200 kPa, VFT = 0.03 kPa or 0.0003 bar For 20 bar or 2000 kPa, VFT = 0.1 kPa or 0.001 bar Vacuum operation is not specified for 600 PSI (40 bar/4000 kPa models and higher. However, all models can be safely connected to vacuum. (Not recommended for continuous use at high vacuum.) Temperature Operating & Compensated: 0°C to 50°C (32°F to 122°F). Storage: -20°C to 70°C (-4°F to 158°F). Electrical Range: 0 to 55 mA Resolution: 0.001 mA Accuracy: ±(0.025% of Reading + 0.001 mA) Percentage Conversion: 4 mA = 0.00%; 20mA = 100.00% or 10 mA = 0.00%; 50 mA = 100.00% Intrinsic Safety Exia Intrinsically Safe, Class I, Groups A, B, C & D, Temperature code T4 Connections Pressure connection: 1/8" female NPT. Electrical connection: 4mm jacks, 19mm (0.75") spacing. Media Compatibility Liquids and gases compatible with PTFE (Polytetrafluoroethylene) penetrated and anodized aluminum sensor manifold, 316 stainless steel (sensor), PTFE can be eliminated, if required, by specifying option SPSS, in which case aluminum manifold(s) will be replaced with stainless steel manifold(s). Note: Over-range occurs at 110% of full scale, causing "HP Over" or "LP Over" to be displayed. Standard factory setting is 1"H2O = 0.036126 PSI (density of water @ 4°C). Specify at time of order if you require a different density (e.g., for water @ 68°F, 1"H2O= 0.036063 PSI). Power Battery: One 9V battery. Battery life: 90 hours typical (alkaline battery). Low battery indicator: Displayed battery icon. Enclosure Description: Extruded Aluminum with sealed membrane keypad. Dimensions: 29mm (1.15") D x 70mm (2.75") W x 130mm (5.4") L Weight: Model 33: 400g (14.0 oz), Model 31: 342g (12.0 oz), Model 31(1500 PSI and above): 360g (13.0 oz) Sensor All welded stainless steel sensor
