MODEL: MLV

MLV SPECIFICATIONS

ES-1356 Rev.8 Page 2/3

http://www.m-system.co.jp/

Excitation adjustment: 6 – 10 Vp-p (front)

■ DISPLAY (Input indicator)

LCD digital display: 0.0 - 100.0 % (min. digit 0.1 %)

(No scaling)

INPUT SPECIFICATIONS

Input: LVDT; 20 – 1000 mV/V at max. deviation; Input

voltage to the MLV must be over 160m Vp-p.

• Excitation: 6 – 10 Vp-p variable (8 Vp-p standard)

Frequency: Approx. 4 kHz

Maximum current: 20 mA r.m.s.

Caution: The input signal may be affected by the type and

length of the cable between the LVDT and the transmitter.

When calibrating the system before installation, use the

same type and length of cable.

If there is an error greater than the described accuracy, or

when you need to change the frequency, please consult

with M-System.

Certain type of LVDT may not be usable with the MLV.

Consult M-System before ordering to confirm the

compatibility.
