The BJ101P Single Channel and BJ202P Dual Channel are direct replacements for the Sigma 9270 1/2-DIN LumigraphTM and 9262 mechanical models. This simplifies retrofitting into existing systems without panel modifications.
For control applications, the optional set point/relay module provides on/off and differential gap control and annunciation using three set points and two Form C relays. The optional digital display reads to 10 percent over and under range.
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.
