Overview
TK-3051TG pressure transmitter material diaphragm: stainless steel 316L, Hastelloy C process connection: stainless steel 316L filling liquid: silicone oil transmitter housing: aluminum alloy material, coated with epoxy resin outer shell sealing ring: nitrile rubber (NBR) nameplate: stainless steel 304 .....
Product Details
The CHD820 series gauge/absolute pressure transmitter is used to measure the liquid level, density, and pressure of liquids, gases, or vapors, and then convert them into 4-20mADC HART current signal output. It can also communicate with HART375 or HART475 handheld controllers for parameter setting, process monitoring, etc.

Range limit
Within the upper and lower limits of the measuring range, it can be adjusted arbitrarily. Suggest selecting range codes with the lowest possible range ratio to optimize performance characteristics.
Zero point setting
The zero point and range can be adjusted to any value within the measurement range in the table, as long as the calibration range is ≥ the minimum range
Installation location impact
Changes in the installation position parallel to the membrane surface will not cause zero drift effects. If the installation position changes by more than 90 degrees from the membrane surface, there will be zero drift within the range of<0.25kPa for range C, and zero drift within the range of<0.15kPa for other ranges. Both can be corrected by adjusting the zero position. No range influence.
output
2-wire system, 4-20mADC, optional HART output digital communication, optional linear or square root output.
Output signal limit: Imin=3.8mA, Imax=20.8mA
alarm current
Low alarm mode (minimum): 3.8mA
High alarm mode (maximum): 20.8 mA
Non reporting mode (hold): Maintain the effective current value before the fault
Alarm current standard setting: high alarm mode
response time
The damping constant of the amplifier component is 0.1s; the time constant of the sensor is 0.1-1.6s, depending on the range and range ratio. The additional adjustable time constant is 0.1 to 60 seconds.
Preheating time:<15s
