Specification


Technical Parameters of 2088 digital LCD pressure transmitter RS485
Output
AnalogTwo-wire 4~20mA DC
Digital quantityTwo-wire 4~20mADC and overlay digital signal in line with the HART protocol
Power supply12.5~45V DC
Load limitLoop Rmax maximum load resistance depends on the power supply voltage. HART communication require the load resistance no less than 250Ω, and no more than 600Ω
Communication distanceThe maximum communication distance is 1.5Km, Multistation communication can take up max15 units smart pressure transmitter
Output displayFour digital display, five LCD display, pointer type
Explosion-proof formBasic type:ExiaII CT5; Explosion-proof type.
Zero shift rangeZero point can be arbitrary positive transfer and negative transfer, but the upper and lower limit of measurement range and pressure range should not be set exceeded
Temperature RangeEnvironmental temperature: -40~85℃ (-20~70℃ when select LCD indicator)
Medium temperature-40~104℃
Static and Unidirectional pressure range3.45Kpa(absolute pressure) 31.2MPa(gauge pressure)
Relative humidity5~98%RH
Start timeStart in 5 second
Capacity changesless than 0.16cm3
Damping adjustment0.20~25
Fault alarmIf there is a breakdown of sensor or circuit, automatic diagnosis function will automatically output 3.9 or 21.0 mA.
Configuration protectionIn order to avoid the transmitter is randomly change the configuration data, can lock the stored data by software or protection switch
Performance indicators
Reference conditionsZero as the lower limit and no migration, the temperature is 25 ℃, the atmospheric pressure, 24 VDC power supply, silicone oil, isolation diaphragm 316 stainless steel, data setting range is the same as the upper and lower limit range
