TH5011T Monocrystalline Silicon Differential Level & Pressure Transmitter
Product description
TH5011T sanitary differential pressure transmitter is used to measure the liquid level, density and pressure of liquid, gas or steam, and then convert it into 4 ～ 20mADC HART current signal output. TH5011T can also communicate with TH5011T handheld terminal or TH100 Modem, and use them for parameter setting and process monitoring.
Standard specification
The range is adjusted based on the standard zero point; the stainless steel 316L diaphragm; filling fluid is silicone oil.

Output | |||
Two wire 4~20mADC output with digital communications, linear or square root programmable. HART FSK protocol are superimposed on the 4~20mADC signal. | |||
Output signal limit：Imin=3.9mA，Imax=20.5mA | |||
Failure Alarm (the mode can be selected) | |||
Low Mode (min)：3.6 mA | |||
High Mode (max)：21 mA | |||
No Mode (hold): Keep the effective value before the fault. | |||
Note: The standard setting of failure alarm is High Mode. | |||
Response Time | |||
The amplifier damping constant is 0.1 sec; the time constant of the sensor and the liquid level flange is | |||
0.2~2s, it depends on the range and range compression ratio. | |||
The additional adjustable time constant is: 0.1 ~ 60s | |||
Preheat time | |||
< 15s | |||
Working condition | Installation Condition | ||
The straight transmitter body can be directly fixed at any position. The best condition is to make the process flange | |||
The axis is in a vertical state, and the position deviation will produce a correctable zero offset. | |||
The case can rotate up to 360° , and the positioning screw can fix it in any position. | |||
The capillary component and the remote flange should only be installed in the same ambient temperature. | |||
The minimum bending radius of the capillary tube is 75mm, and winding is strictly prohibited. | |||

Filling fluid | Density（25℃） | Range of working temperature | |
Silicon oil | 960kg/m3 | -30~200℃ | |
Vegetable oil | 937kg/m3 | 0~250℃ | |
Pressure limit | |||
From 3.5kPa absolute pressure to rated pressure | |||
Unilateral overload limit | |||
The low-pressure side is the rated pressure of the transmitter body, and the high-pressure side is the rated force of the remote flange, which may have a correctable zero drift. | |||
