LDN200 Economic pressure transmitter is a practical product with low cost, high precision and high reliability, adopting ceramic strain gauge sensor. Especially recommended to be used in corrosive media. The product has the characteristics of standardized interface form, small size, anti-interference, low price, light weight and easy installation. It is widely used in industrial fields or laboratories, and is suitable for pressure measurement of gases and liquids that can contact some compatible materials.
The LDN200 is an economical pressure transmitter that uses a ceramic piezoresistive sensor. It is designed for low cost, high accuracy and high reliability, making it suitable for industrial and laboratory applications involving gas or liquid pressure measurement.
Key features include a small size, robust anti‑interference design, lightweight construction, and easy installation. It supports gauge, absolute and negative pressure measurements with selectable ranges from -100 kPa up to 60 MPa, and provides either 4‑20 mA (two‑wire) or 1‑5 V (three‑wire) output signals. Various pressure interfaces and connector options are available to match different installation needs. This manual is written in Chinese.
| Pressure range | -100 kPa to 60 MPa |
|---|---|
| Output signal | 4–20 mA or 1–5 V |
| Sensor type | Ceramic piezoresistive |
| Supply voltage | 18–36 V DC |
| Connector type | Hirschminn, Hummel |
It covers a range from -100 kPa up to 60 MPa, with selectable sub‑ranges such as 0–10 bar, 0–20 bar, etc.
The transmitter can output either a 4–20 mA signal (two‑wire) or a 1–5 V signal (three‑wire).
In two‑wire mode, pin 1 is power +, pin 2 is signal +, pin 4 is the shielded case, and pin 3 is not used.
