Product Detail
Capacitance pressure sensor Measuring range: 0~1.6Kpa; 0~6Kpa; 0~40Kpa; 0~200Kpa; 0~1000Kpa; 0~2Mpa; 0~10Mpa, 0~25Mpa

Capacitance pressure sensor 

Mainly Technical indicators

Useful object  liquid, gas or steam

Measuring range  see type spectrum table

Positive-negative offset Maximum positive offset is 500%, Maximum negative offset is 600%

Positive negative zero migration of  DP √P is ±10% of flow range. AP type only has mass positive offset and is 500%

Temperature scope Operating temperature of filling silicon oil measuring element -40~104°C                 Operating temperature of filling inertia oil measuring element -18~71°C                 Storage temperature -51~121°CRelative humidity 1~100%

Volume variables less than 0.16 cm3

Insensitivity zone None

Stability  don’t exceed the accuracy of the transmitter within 6 months

Temperature influence  at maximum measure(e.g. 0~40kPa)

Zero error is ±0.5%55°C

Total error (include span and zero error—the same below) is ±1%55°C

Note DP3 for twice of above-mentioned influence,

zero error of DR2 at the maximum measure (0~7.46 KPa) is ±1%28°C,total error is±1%28°Cof span

For DP √P type transmitter is at high span, only considering total error of which value is±2.5%55°C

At minimum range(e.g. range 4  0~6kPa)

Zero error is ±3%55°C

Total error is ±3.5%55°C

Note DP3 for twice of above mentioned influence

Static pressure influence static pressure influence for DP,DP  √P,HP,DR see the following table
