Eclipse Locktite Automatic Shutoff Gas Valve

An essential part of a reliable glass furnace safety system. This Eclipse manual reset, gas shut-off valve shuts off the gas supply in response to a power outage, or a signal from a flame safety relay or other safety device. The gas stays off until the unsafe situation is corrected and the valve is manually turned back on. UL listed for natural gas, LP gas and hydrogen, 30psi maximum pressure. 2" threaded iron pipe fitting. Has an internal relay with two outputs for alarms, automatic phone dialer, or whatever. You can use this link to download the installation guide for this valve from the Eclipse Combustion website. The spec sheet is in Adobe PDF format.

New/unused. Model 208LT-IS (2 inch fittings).

Watlow Anafaze 8CLS Temperature Controller

Eight fully independent control channels - control 8 separate ovens and/or furnaces at once! User configurable for six different thermocouple types (J,K,R,S,T,B); PID control (with autotune), time proportional, on/off, and distributed zero crossing* (DZC) output - DC millivolt and milliamp analog output is available with the optional Watlow/Anafaze Dual DAC converter (below); Multiple, user programmable alarm and event outputs per channel. Store up to different 8 jobs (programs) in memory, and access them by entering a job number. Each job is a set of operating conditions, including setpoints and alarms. RS-232 / RS-485 serial interface (user selectable ) included for monitoring or control with your computer (software not included).

Add the optional ramp/soak EPROM (available from Watlow) and you have a unit that makes a Digitry GB4 look like something found at Toys 'R Us. (The catch being that the Watlow is correspondingly difficult to program due to the multitude of setup options.)

The 8CLS is essentially the same as the model that replaced it three years ago, the CLS208, with very few changes. The spec sheet for the CLS208, in Adobe PDF format, is available on the Watlow website. Unfortunately, info for the 8CLS is not there, but the specs are virtually identical to those listed in the spec sheet for the CLS208. The price of a CLS208 (without ramp/soak) is in the $2200 neighborhood. You can also download the manual for the CLS208. The 8CLS manual is available by mail from Watlow.

1/8 DIN size; 2 line/16 characters per line, backlit LCD display with plain English readout and programming prompts (not hard-to-decipher codes and symbols). Factory set up with 6 input channels as 0-20mA and 2 as thermocouple. Any, or all, of the milliamp inputs can be changed to thermocouple input by simply clipping a resistor on the circuit board. (I can do it for you if you aren't comfortable doing it yourself.)

Brand new in the box, includes 12V power supply, 50 terminal output block with ribbon cable, user's manual and mounting brackets. I have one left.
Price reduction!!! $500 plus shipping

******************

I also have a couple of used Anafaze Dual DAC digital to analog converters for these. They convert the DZC output signal of an 8CLS to a 4-20 milliamp signal for driving the DIN-a-mite SCR's below, or anything else that needs a 4-20 milliamp control signal (like a motorized gas proportioning valve). Each of 2 separate output channels can also be independently configured for either 0-5V or 0-10V DC output by moving a jumper on the board. These are a $200 item, when new. The buyer(s) of the new 8CLS controllers will have the first option on these at $35 each. After the controllers are sold, I will offer any remaining Dual DACs for $65 each.

*DZC output is capable of sending 60 DC pulses per second (one every AC line cycle) to drive solid state relays for extremely precise temperature control. With this output you can use a comparatively low cost zero-crossing solid state selay to mimic an expensive zero-fired SCR power controller.

Omega type "K" Quick Disconnect Thermocouples

New/unused Omega Engineering type "K" thermocouples with quick disconnect mini plug (male) and inconel sheath. Omega part number KMQIN-MO8OU-800-IEC (metric part number - equivalent to KMQIN-032U-32). 800 millimeters (32 inches) long, sheath outside diameter 0.80mm (0.032 in). Thermocouple plug color is pale green instead of the USA standard yellow. Pale green is the international color coding for "K" type thermocouple plugs. Will mate with any "K" type plug that accepts mini connectors. Yellow female plug "K" type is also included so you don't have to hunt one down.. Fine wire diameter reacts very quickly to temperature changes. Made with special limits of error thermocouple wire for maximum accuracy. Can be bent to nearly any shape and will maintain that shape. Excellent for a lampworking (or any other type) oven that needs a highly accurate, fast response thermocouple. Mini quick disconnect plug on thermocouple is Omega part number SMP-K-M. Price of these thermocouples in the 2001 Omega catalog is over $32 each. I have about 2 dozen. $15.00 each, plus shipping

Banner Q85VR3LP retro-reflective photoelectric Switch

Brand new in the box, Banner Q85VR3LP retro-reflective photoelectric switch. I use a retro-reflective photoswitch on my electric glass furnace to kill the power to the elements when I open the door to gather. I have found this to be much more reliable than the microswitch I used on my original furnace (and discarded after less than a year). The Q85VR3LP on my current glass furnace has operated for several years without a problem. Be aware that Banner recommends against the use of any of their photoswitches other than their special Machine-Guard series (at mega$$$) as personal safety devices. Regardless, I still use one myself. Banner is known for making very reliable equipment. They can also be used on the doors to your studio to ring a bell or buzzer when someone walks in, which is what I did. They have any number of other uses as well. Specs: Polarized retro-reflective sensor with metal bracket and mounting hardware Range: 15 feet Operating voltage: 12-240Vdc or 24-240Vac Output type/rating: Electro-mechanical relay, 250Vac/30Vdc at 3 amps switching capacity Sensitivity adjustment dial 2 LED status indicators on top of unit User selectable "light on" or "light off" operation Overall size ~ 3.3 x 2.5 x 1 inch Reflector is not included, but a bicycle reflector from your local hardware store or WallyWorld will work. White or clear is probably best, although I've tried blue, green, and yellow as well, which have also worked. Just don't use a red one - it won't work because the red reflector cancels out the red light beam. The regular retail price of this model is $95 each. SOLD OUT!

Idec ISF-P03M U Polarized Retro-reflective Photoelectric Switch

Operating range: 10 feet Output type: internal single pole double-throw (SPDT) relay, 3 Amps @ 250 Vac or 30 Vdc. Input Supply voltage: 24-240 Vac or Vdc Red Indicator LED indicates operation. Switch selectable “light on” or “dark on” operation. Includes 2 x 2 inch square reflector, instructions/spec sheet, and mounting kit. SOLD OUT!

Eclipse UV Flame Sensing Control

Eclipse Controls Ultra-Violet Flame Sensing Control. Model number 5605-32, no purge. For use in a flame safety system with an ultra-violet flame detector and gas shutoff valve (like the Eclipse Locktite valve above) to safely shut down the gas supply to a burner if there is a loss of flame. Also requires Eclipse wiring base for electrical connections. $75 each. (I have two.)
