363L Series Monocrystalline Silicon Flange Mounted Transmitter

Performance

The overall performance is based on the combined error of reference accuracy, ambient temperature influence, and range static pressure influence.

Accuracy index

± 0.075% FS range (conventional)

Specific performance indicators

(Zero-based range, reference conditions, silicone oil-filled liquid, 316 stainless steel isolation diaphragm, 4-20mA analog output, digital trim value equal to range setpoint value.)

Accuracy

(Reference accuracy includes hysteresis, terminal-based linearity, setting capability, and repeatability)

  ± 0.075% of range

If the range is less than X

± [0.025 + 0.05 (X / range)]%

X value

Damping time constant

The total damping time constant is equal to the sum of the damping time constants of the amplifier components and the capsule. The damping time constant of the amplifier component is adjustable in the range of 0 to 100 seconds.

Capsule (silicone oil)

Time constant (second) (time constant can be set according to the actual situation on site, 1S is recommended)

Influence of installation position

The change in the installation position parallel to the diaphragm surface will not cause zero drift. If the installation position and the diaphragm surface change by more than 90 °, the zero drift in the range of 0.4KPa can be corrected by zero adjustment without affecting the range.

Power impact

Less than ± 0.005% of range / volt

Range and sensor limits

Table 1.363L range and sensor limit values

Zero and span adjustment requirements

· Zero and span values can be set arbitrarily within the span limits indicated in Table 1.

• The range must be greater than or equal to the minimum range indicated in Table 1.

Application occasion

Measurement of liquid, gas and steam

Output

The second line is 4-20mA, user-selectable linear. The digital process variable is superimposed on the 4-20mA signal and is suitable for any host using the HART protocol.

power supply

Requires external power. The standard transmitter (4-20mA) operates at 14.5-45V dc with no load.

Loop load limit

The maximum loop resistance is determined by the external power supply voltage and the relationship is as follows:

Note: The supply voltage range of the transmitter with backlight display is 14.5 ～ 45V

Intrinsically safe transmitter power supply voltage range is 14.5 ～ 28V

The working voltage during HART communication should be greater than 17.5V

Static pressure limit and maximum overpressure

For type 363L limit value is 0psia to flange rating or sensor

The smaller of the rated pressure values.

Failure mode

Output code

If the sensor or microprocessor malfunctions, the transmitter will drive a high or low alarm signal to remind the user. The alarm output value depends on the factory configuration of the transmitter:

Linear output: 3.8 <I <20.8

C4: I = 20.8mA high fault

CN: I = 3.8mA low fault
