Description

SX20MD Series

High performance, high stability LVDTs with digital and analogue outputs. Strokes from +/- 2.5mm to +/- 150mm. Outside diameter – 20mm. 0 – 10V and 4 – 20mA analogue outputs, RS485 Modbus digital communication protocol. Digital hybrid module corrects for thermal drift and non- linearity errors, M12

The Meggitt (Sensorex) SX20MD combines the advantages of LVDT technology (strength, reliability, contactless) with digital electronics.

The output signal, which is proportional to the core rod position, is available as both analogue (0/10V and 4/20mA) and digital (RS485) in ‘modbus’ protocol. All three signals can be used at the same time.

A digital hybrid module (HCN) is used to improve the sensor’s accuracy, notably the thermal drift and non-linearity.

This allows a non-linearity better than ±0.05% of full scale on the output signal.

Measurement range is from ±2.5mm to ±150mm.

Gauge head kit is supplied as standard (without spring return for stroke 300mm).
