pla series amplified precision very low pressure sensors 2/4 e / 11735 / 0 www.sensortechnics.com specification notes: 1. 2. 3. 4. 5. 6. 7. reference conditions: supply voltage v s = 5.00 v, t a = 25c, common-mode pressure 0, pressure applied to port b. proof pressure is the maximum pressure which may be applied without causing durable shifts of the electrical parameters of the sensing element. burst pressure is the maximum pressure which may be applied without causing damage to the sensing element or leaks from the housing. full scale span is the algebraic difference between the output voltage at full-scale pressure and the output at zero pressure. the output voltage of the sensor is ratiometric or proportional to the excitation voltage. for these models all specifications will change proportionally to any changes in the excitation voltage. the excitation may vary between 4.5 to 5.5 v. all specification s will nominally be change by a ratio of v excitation / 5.0 v. for example, if 5.5 v excitation then both, the full scale output voltage and the offset voltage, would be 5.5/5 th of the specified value. non-linearity refers to the b est s traight l ine fit measured for offset pressure, full-scale pressure and ? full-scale pressure. shifts relative to 25c. shifts within the first hour of excitation applied to the sensor. pressure sensor characteristics 1 . o n t r a pe r u s s e r p g n i t a r e p oe r u s s e r p f o o r p 2 e r u s s e r p t s r u b 3 b d 1 0 0 m a l pr a b m 1 . . . 0h " 0 0 1 . . . 0 2 oh " 0 0 2 . . . 0 2 o b d 1 0 0 h a l ph " 1 . . . 0 2 oh " 0 0 1 . . . 0 2 oh " 0 0 2 . . . 0 2 o b d 5 x 2 h a l ph " 5 . 2 . . . 0 2 oh " 0 0 2 . . . 0 2 oh " 0 0 3 . . . 0 2 o b d 5 0 0 h a l ph " 5 . . . 0 2 oh " 0 0 2 . . . 0 2 oh " 0 0 3 . . . 0 2 o b d 0 1 0 h a l ph " 0 1 . . . 0 2 oh " 0 0 2 . . . 0 2 oh " 0 0 3 . . . 0 2 o b d 0 2 0 h a l ph " 0 2 . . . 0 2 oh " 0 0 3 . . . 0 2 oh " 0 0 5 . . . 0 2 o b d 0 3 0 h a l ph " 0 3 . . . 0 2 oh " 0 0 5 . . . 0 2 oh " 0 0 8 . . . 0 2 o u d 1 0 0 h a l ph " 1 . . . 0 2 oh " 0 0 1 . . . 0 2 oh " 0 0 2 . . . 0 2 o u d 5 0 0 h a l ph " 5 . . . 0 2 oh " 0 0 2 . . . 0 2 oh " 0 0 3 . . . 0 2 o u d 0 1 0 h a l ph " 0 1 . . . 0 2 oh " 0 0 2 . . . 0 2 oh " 0 0 3 . . . 0 2 o u d 0 2 0 h a l ph " 0 2 . . . 0 2 oh " 0 0 3 . . . 0 2 oh " 0 0 5 . . . 0 2 o u d 0 3 0 h a l ph " 0 3 . . . 0 2 oh " 0 0 5 . . . 0 2 oh " 0 0 8 . . . 0 2 o
