ATM Pressure Converters - PX1 series

    Pressure converters (PX1 series) are manufactured basing on high classes semi-conductor pressure sensors. They are especially appropriated to cooperation with microprocessor data collection systems equipped in digitizer. Sensors are secure before exit short-circuit and opposite power supplies connecting. Exit-voltage characteristic (in pressure function) is linear. Converters characterize big persistence, reliability and invariability of characteristics. During all period of exploitation they will not require of calibrating.  

Converters pressure characteristics 

Converter	Nominal pressure range	Max. pressure	Limit pressure	Unit
PX1A	0¸500	2000	3500	kPa
PX1B	0¸1000	4000	6000	kPa

Attention: 
Offence max. pressure can fixedly to damage transducer or to make worse his characteristics. 

Additionally converters can be made on following nominal pressure ranges:

• 0¸10  kPa
• 0¸50  kPa
• 0¸100 kPa
• 0¸700 kPa

Exit-voltage characteristic (in pressure function) is definite as follows:

PX1A Uwy=Uzas* (0,0018* P[kPa]+0,04)± D U

PX1B Uwy=Uzas* (0,000901* P[kPa]+0,04)± D U

PX1A converter

PX1B converter

Converter exactitude (in temperature function):
 D U (-40...+125 0C) = D U (0...85 0C)* multiplier
