Transmitter Models 
Differential Pressure - LD400D and LD400H
Pressure is applied to high and low side and differential pressure is measured. High static pressure is supported for LD400H models.

Flow - LD400D and LD400H
The differential pressure is generated by a primary flow element and the square root function computes the flow measurement.

Absolute Pressure - LD400A
The pressure is measured at the high side of the transmitter and the low side is at zero absolute pressure to a sealed chamber with vacuum.

Gage Pressure - LD400M
The pressure is measured at the high side of the transmitter and the low side is open to the atmosphere, providing true local atmospheric reference.

Level - LD400L
The transmitter has a flange-mounted unit for direct installation on vessels. Extended diaphragms are also available. The closed tank low side can compensate for ullage pressure.

Sanitary - LD400S
LD400S is especially designed for food and other applications where sanitary connections are required. With threaded or "tri-clamp" connections, it allows quick and easy cleaning and maintenance.

The flush connection enables deposit removal without disconnecting the seal. Tri-clamp and other connections are compliant to 3A (74-02) standard for food grade applications.
