1. Main features

Complete in varieties and specifications, high precision, good stability

Two-wire system (four-wire system in special situations)

Sensitive elements, plug-in circuit boards, components can be interchanged with imported 1151 products of the same kind.

The range and zero position can be adjusted continuously externally

Positive transfer up to 500%, negative transfer up to 600%;

Adjustable damping;        

3-digit LCD liquid crystal display and pointer indicator show the measurement results

2. Function parameters

Object: liquid, gas and steam
Measuring range: see selection table

Output signal: 4 ~ 20mADC ( four-wire system220V, AC power supply, 0 ~ 10mADC output)
Power supply: 12 ~ 45VDC, usually 24VDC
Load characteristics: related to the power supply, with load capacity at a certain power supply voltage, the relation between load impedance RL and power source voltage VS is RL<50 (VS-12)
Display instrument: pointer type linear indication 0 ~ 100% scale and square root indication 0-10 scale, and the 3-digit liquid crystal display (0 ～ 100% linear), 3 LED (0-100% linear or range mode)

Range and zero: externally, continuously adjustable
Positive and negative transfer: after the zero has gone through positive transfer or negative transfer, the absolute value of the upper limit and lower limit of the range and measuring range can not exceed 100% of the upper limit of the measuring range; maximum positive transfer amount should be 500% of the minimumadjusting range; maximum negative transfer amount for 500% of the minimum adjusting range; maximum positive and negative transfer amount of the flow transmitter should be 10% of calibration range.

Temperature range: general transmitter-25C ~ +70C.
Static pressure and overload pressure: the differential pressure transmitter can bear maximum static working pressure, and the transmitter will not be damaged.
Volume variation: <0.16cm³

Damping time: generally adjustable between 0.2S to 1.67S
Start-up time: 2S no need preheating
