Product features 

● Output signal: Two-wire system 4～20mA; 

● Power supply: 12～45VDC; 

● Power supply effect: <0.005%/V; 

● Load effect: No load effect when the power supply is stable; 

● Measurement accuracy: ±0.2%, ±0.25% and ±0.5% of calibration range (if the standard precision is ±0.5%, other precision chosen shall be indicated at the time of ordering goods and model selection.); 

● Transfer characteristic: Maximum positive transfer is 500% and maximum negative transfer is 600%; 

* The absolute value of negative transfer isn't greater than one technical atmosphere. 

* The absolute value of the upper or lower limit after transfer shall not exceed the upper limit of maximum measurement scope; 

* The negative transfer of the absolute pressure transmitter is forbidden; 

● Damping: Generally adjustable within 0.2～1.67s. The time constant will increase in case of filling with inert liquid or being with remote transmission device; 

● Startup time: ﹤2s without preheating; 

● Working environment: Ambient temperature: -29～93℃ (analogue amplifier), -29～65℃ (with display meter head), ambient humidity: 0～95%; 

● Protection characteristics: IP65; 

● Anti-explosion type: Flame-proof type ExdIIBT4, intrinsic safety type ExiaIICT4; 

● Influence of static pressure: Zero error: ±0.5% Maximum range limit. As for 32MPa, the correction can be conducted by zero setting under the pipeline pressure; 

● Effect of electromagnetic radiation: 0.05% maximum range, received radiation frequency: 27～500MHz, test field strength: 3V/m; 

● Influence of vibration: ±0.05%/g in case of 200Hz vibration in any direction; 

● Mounting position: The diaphragm isn't subject to vertical installation and the zero error of less than 0.24KPa may be produced, but can be removed by zero setting.
