Product Description
Boiler Conductivity Replacement Probes
The below conductivity probes are direct replacements for current conductivity probes for boilers. Please be aware of temperature compensation and wire configuration. If you have any questions about selecting the correct probe, you may CONTACT US by clicking on the hyperlink and completing the form.
BE-2 Boiler Probes Stainless steel 1” MNPT bushing and PEEK construction, 75 psi (5.17 bar) max: BE-2 no temperature compensation.
BE-32 and BE-4RTD Boiler Probes Stainless steel and PEEK construction, 3/4” MNPT supplied with 1” bushing; 250 psi (17.2 bar), 400°F (204°C) max. BE-32 no temperature compensation, BE-4RTD uses RTD temperature compensation.
BE-H2-S and BE-H4RTD-S Boiler Probes Stainless steel and PEEK construction, 3/4” MNPT; 600 psi (41.3 bar) max
BE-32-S and BE-4RTD-S Boiler Probes Slightly shorter model of the BE-32 and BE-4RTD. Stainless steel and PEEK construction, 3/4” MNPT supplied with 1” bushing; 250 psi (17.2 bar), 400°F (204°C) max. BE-32-S no temperature compensation, BE-4RTD-S uses RTD temperature compensation
Notes:
1. Thermistor style temperature compensation: A = 32°-140°F (0°-60°C), B = 32°-212°F (0°-100°C).
2. RTD temperature compensation is only available on MegaTron and MegaTron XS controllers.
3. Number of wires per probe: -1 or -2 = 2 wires; -4 = 4 wires.
4. RTD probes require six conductors ran from controller to probe.
Wiring for Temperature Compensated Probes
- -A4 and -A4SS probes: Red and black for conductivity, and white and green for temperature.
- AH-075-4ASS-10 probe: White and green for conductivity, and red and black for temperature.
- -4B and -4BSS probes: Red and black for conductivity, and white and green for temperature.
- AL-4RTD probes: Red and black for conductivity, and white, green and clear for temperature.
- BE-4RTD and BE-4RTD-S probes: Black & white for conductivity, and red & green for temperature. Six conductor wire must be run from probe to controller.
- BE-34B probes: Red and blue for conductivity, green and white for temperature.
