Advantages and technical parameters of the 3351 transmitter

Thread Content

Technical specifications of 3351 transmitter 　⊙Application areas: liquids, gases, and steam； 　⊙Measurement range: 0-100Pa to 40Mpa ； 　⊙Output signal: 4-20mA ； 　⊙Power supply: 12-45V DC, typically 24V DC ； 　⊙Load characteristics: The relationship between the load impedance RL and the supply voltage VS is given by: RL ≤ 50(VS – 12) Ω ； 　⊙Indicator gauge: Pointer-type linear indication on a 0-100% scale and square root indication on a 0-10 scale ； 　⊙Range and zero point: externally continuously adjustable ； 　　 Positive and negative migration: After the zero point shifts positively, the absolute values of the upper and lower limits of the range and measurement scale must not exceed 100% of the upper limit of the measurement range. 　　 The maximum positive migration amount is 500% of the calibration range ； The maximum negative migration is 600% of the minimum calibration range.
