DESCRIPTION
A Tek-Hydro 4500A-G series gauge pressure level transmitter is a commonly used instrument which measures the level of a liquid in a tank. It is a simple device used in a wide range of liquids, including corrosive, non-corrosive and abrasive liquids and slurries in tanks of any size. It can handle broad temperature and pressure ranges under different process conditions. It is used to measures not only the liquid level but also other parameters such as the flow rate and density. This transmitter has a maximum pressure up to 8700PSI.
Features
- Operator can calibrate device using zero/span button, no handheld calibrator required
- Digital communication HART® protocol
- Fail-safe mode process function for detecting any abnormal condition occurring
- Superior performance provides High accuracy up to ±0.075%
- Automatic ambient temperature compensation improves performance of device
- Various Output: 4-20 mA, digital signals
- The mounting bracket can be rotated up to 360º and LCD display up to 270º
- EEPROM write protection
- Explosion proof approval and intrinsic safety approval
