Tubine flowmeter Technical parameter and connection terminals of Type LWF-(Ⅰ) (current output)

 

preamplifier

 

(1)Type LWF-(Ⅰ)-1 preamplifier output 4~20mA current analog signals, three-wire system. 

Before leaving the factory, each amplifier has been calibrated together with associated turbine 

flow meter. In order to ensure the accuracy, mixed use is not allowed.

 

0 Operating power supply:VDD=+11~26VDC

 

0 Output signal: current output I=4~20mA

 

Intrinsic error :±0.5% full scale value

 

Load resistance:0~RΩ(R=50(VDC-11)+250)

Operating condition: ambient temperature:-25~+55℃;

 

Relative humidity≯85%RH

 

Installation: Installed on the body of flow meter

 

through M16X1 thread and slightly locked with locknuts.

 Note: The thick black line is used to shield outside interference and must be earthed!

 

(2)Type LWF-Ⅰ-2 pre-amplifier may simultaneously output current and pulse signals and can drive 

the PLC controller, and besides, it has explosion proof function and anti-spray function.

 

0 Operating power supply:VDD=+11~26VDC


   ● Output signal: current output I=4~20mA Pulse output: Wave form: square wave Low electrical level: ≤1V

 

High level:power supply voltage-3V

 

●Ambient temperature:-25~55℃
