Spiratec ST14, ST16 and ST17 Sensor Chambers and Sensors
Spiratec sensor chamber description The Spiratec trap fault detection system is designed to operate on saturated steam systems only, to indicate whether a steam trap is leaking steam. When combined with the R1C or R16C automatic trap monitor and WLS1 waterlogging sensor assembly, it will detect if a steam trap has failed closed or is blocked. As standard - The sensor chamber has the sensor connection on the right hand side of the chamber when viewed from the direction of flow. If required - Chambers can be supplied with the sensor connections on the left hand side 'L', but must be requested when placing an order, i.e. ½" ST141L. Chambers are available in two configurations: 1. Fitted with an SS1 standard sensor for steam leak detection only. 2. Without a sensor fitted. A WLS1 waterlogging sensor assembly is available separately for steam leak and waterlogging applications. Spiratec sensor description Spiratec sensors are designed to fit into Spiratec sensor chambers as part of the Spiratec trap fault detection system. Available types:
Sensor chamber
SS1 standard sensor: For the detection of steam leaks when used in conjunction with a sensor chamber and a Type 30 or Type 40 hand held indicator, R1C or R16C automatic trap monitor. SS1's are normally supplied already fitted into the sensor chamber. WLS1 waterlogging sensor assembly: For the detection of steam leaks or traps that have failed closed or are blocked when used in conjunction with an R1C or R16C automatic trap monitor. WLS1's are normally supplied as separate items for fitting into a sensor chamber on site. Note: sensor chambers without sensors are available from stock. Optional extras A sensor blanking plug is available at extra cost, to protect the external connection of the SS1 standard sensor chamber from dirt.

R1C Steam Trap Failure Monitor
Description The R1C steam trap failure monitor will monitor the performance of a single steam trap when used in conjunction with a Spiratec sensor chamber and sensor or a steam trap with integral sensor. It will indicate whether a trap is operating correctly, passing live steam or has failed closed by means of coloured trap status lights on the unit. Analogue and digital outputs allow it to be connected directly to BEMS/EMS to indicate steam trap status remotely. System components To detect a steam trap that is leaking steam, a standard SS1 Spiratec sensor is installed in a sensor chamber or steam trap. To detect a steam trap that is leaking steam or is waterlogged, a WLS1 Spiratec waterlogging sensor assembly is installed in a sensor chamber or steam trap. R1C system installation The R1C must be installed in a steel conduit system within 10 m (32.8 ft) of the Spiratec sensor. Connections The R1C enclosure is a circular conduit box with M20 threaded entry holes. To maintain resistance to moisture, use a suitable cable gland between the R1C and the Spiratec sensor (Type SS1 or WLS1). If the cable to the BEMS/EMS passes through a conduit, make sure that the threaded connection to the R1C is water-tight to maintain the IP65 enclosure rating. Details of electrical connection are supplied with the product.

In addition it can be disabled if required. As supplied, the R1C comes factory set as follows: Channel Failure detection Notes Leak detection period 22 minutes
The trap must leak steam for 22 minutes before the R1C signals a fault.
The conductivity of the condensate in the sensor chamber must be greater than 4.8 microsiemens for correct operation. The condensate in the sensor chamber must cool below this temperature before the R1C signals a waterlogging fault.

Output signals for remote indication of trap status Digital outputs PNP open collector output
Use this output to connect the R1C to a BEMS / EMS whose digital inputs are pulled down to 0 volts. The pnp outputs act like switches connected to the R1C's power supply. During normal trap operation, the pnp outputs will switch ON and give out a voltage equal to the R1C's power supply minus 0.4 V. Their output resistance in this state is 220 ohms. If the trap fails, one of the pnp digital outputs will switch OFF. NPN open collector outputs Use this output option to connect the R1C to a BEMS / EMS whose digital inputs are pulled up to a positive voltage. The npn outputs act like switches connected to 0 volts. During normal trap operation, the npn outputs will switch ON, giving out 0 volts with an output resistance of 220 ohms. If the trap fails, one of the npn digital outputs will switch OFF.

Spiratec Type 30 and Type 40 Trap Failure Indicators
Description The Spiratec Type 30 and Type 40 trap failure indicators are used for the detection of steam leaks through steam traps. They are used with: - a sensor chamber and sensor, installed immediately upstream of a steam trap. - a steam trap with a built-in sensor. A remote test point (Spirax Sarco R1 or R12) can be used where access to the trap or chamber is difficult. Three versions of the indicator are available: Spiratec Type 30 Spiratec Type 30 UL approved (described in separate literature) Spiratec Type 40
5.1.15
The Type 40 is similar to the Type 30, but the Type 40 has an electronic filter to give a steady response where fluctuating pipeline conditions may cause a less stable signal. Type 30 and Type 40 indicators are battery powered, and are connected to the sensor using the 1.25 m (4.1 ft) cable provided. The trap status is indicated with red and/or green LEDs. A test circuit indicates low battery or a faulty unit.

Spiratec R16C Automatic Steam Trap Monitor
Description The Spiratec R16C is an automatic steam trap monitor for up to 16 steam traps. Remotely mounted, it continuously scans electronically up to 16 Spiratec sensors and indicates when steam wastage or waterlogging occurs at any of the traps being monitored. A sensor is screwed into each sensor chamber or steam trap and is connected by wiring to the R16C which is sited at a convenient point. When all the steam traps being monitored are working correctly a single green light will be illuminated. If one or more of the steam traps is failing, then the corresponding 'fail' lights (of which there are thirty two) are illuminated and the green light is extinguished. The R16C, which operates continuously, will indicate that either all the traps are operating correctly, or that there is a failure of any particular identified trap or traps. The unit can be interfaced with most computer controlled Building Management Systems, through a pair of volt free contacts, which will open on trap failure. Available types R16C steam trap monitor is available as standard for use with low voltage supplies at 24 Vac. The monitor is supplied for wall or panel mounting.
