BJ101P-BJ202P Replaces Sigma 9270 DIN Versatile VMI 2000

BJ202P-dual
The BJ101P (single) and BJ202P (dual) are direct replacements for the Sigma 9270 1/2-DIN LumigraphTM and 9262 mechanical models. This simplifies retrofit into existing systems without panel modifications.

For control applications, the optional set point/relay module provides on/off and differential gap control and annunciationusing three set points and two Form C relays. The optional digital display reads to 10 percent over- and underrange.

The optional temperature measurement module makes the instrument a direct-reading indicator for E, J, K, and T thermocouples, or 100-ohm RTD, and an optional re-transmission module simplifies distribution of the temperature parameter throughout the system.
