20 K ohm Pipe sensor REPLACES PS20
Check up on the furnace operation, heating system diagnostic test point interface, hot water or steam pressure boilers with Honeywell's compatible replacement 535-34AB08-203 20 K ohm Pipe sensor REPLACES PS20 . This product is a level 2 diagnostic device for heating systems and includes an internal 0.0061 in. (0.15 mm) NPT pipe thread fitting and wire leads to connect to terminals. This Honeywell part is offered in a variety of configurations depending on your specific needs.
This HONEYWELL 20 K ohm Pipe sensor REPLACES PS20 has a resistance of 20 ohms (W20). It is in the category of low power and Sensing Resistors, and has a Non-Magnetic Probe (SMP).
Honeywell (PS20) 20 K ohm pipe sensor replaces PS20 to sense liquid level of steam, hot water, and oil.
Honeywell's F5020/PS20 Pipe sensor is an ideal replacement for the pipe sensor on most F-Series thermostats. The F5020 is a single-threaded diaphragm, which is easy to install and can be used up to 120°F (49°C). Because of its compact size, it can be installed in tight spaces.
The PS20 is a 20 kOhm RTD Temperature Sensor. This temperature sensor is a smart sensor that has no moving parts, eliminating the need to move or clean the sensor. The PS20 is a fast responding, stable and reliable device with virtually no maintenance required. It requires 4-wire connection (power and 3-wire), no additional hardware needed.
The Honeywell PS20 pipe sensor, a part of the SENTRON FF2+S and FF2+C gas detectors, is a programmable transmitter with parts that are sold separately. The PS20 measures hazardous low-level combustible gases in pipe systems and alerts operators to leaks.
Where a pipe is subjected to movement the PS20 can give false readings. It is recommended that where there is potential for large movement on piping systems that the RTC5 pipe sensor should be used. The RTC5 pipe sensor has a jam clearance feature which reduces false alarms by allowing the pipe to move without causing an alarm.
