The Simple Apparatus referenced in these pages is the RTD temperature sensor. 704, "CONTROL DOCUMENT, SYSTEM APPROVALS FOR INTRINSICALLY SAFE TRANSMITTERS" on pages 5-7 of this manual. 2) If installing transmitters in a Class I, Division 1 hazardous area, then refer to Minco INST. Per Factory Mutual, 1) Installation shall be in accord with these instructions and the National Electric Code. Read these instructions thoroughly before installing transmitters in a hazardous area. Wiring Diagram Installation of TT176, TT216, and TT676 Temptrans TM in Class I, Divisions 1 or 2, Groups A, B, C, and D hazardous locations. Do not change its zero and span adjustments. For models TT176 and TT676, the Temptran has been factory-calibrated for its marked temperature range or else for a specific RTD. The RTD connections for the Temptran in the wiring diagram below must be connected as shown or the transmitter will not function properly. Connect the Temptran as shown below, observing the +/- polarity of the current loop. Mount with #8 machine screws using the two mounting holes provided in the transmitter case. Locate the Temptran near the RTD, in an area where the ambient temperature stays between -40 and 85 C (-40 and 185 F). Refer to pages 3-7 for further information on installing these transmitters in a hazardous location. Installation If installing the Temptran in a hazardous location, the installer must adhere to installation requirements as set forth by the National Electrical Code (NEC) and any other applicable codes and standards. Request Minco Application Aid 15 for more information. The leads that supply power also carry the current signal. The current changes according to the range marked on the Temptran: 4 ma at the lowest temperature of the range, rising to 20 ma at the top of the range. The Temptran TM converts the RTD's signal into a 4 to 20 ma current. These transmitters are FM-approved for use in Class I, Divisions 1 & 2, Groups A, B, C, and D hazardous locations and appear in the approval guide as IS/I/1/ABCD and NI/I/2/ABCD. Telephone: (763) / FAX: (763)Ģ Description Models TT176, TT216, and TT676 are 2-wire temperature transmitters for RTD (resistance temperature detector) thermometers. Set point adjustment and/or manual override buttons are available on wall mount sensors.Ī plug-in display that can be universally applied to all MBS, AKS and MBT transmitters with a 4–20 mA output and a plug connection according to EN 175301-803-A.1 MINCO TT176, TT216, and TT676 2-wire Temperature Transmitters Installation and Operating Instructions INTRINSICALLY SAFE NON-INCENDIVE TT216 TT176/TT676 MINCO MINCO PRODUCTS, INC Commerce Lane, Minneapolis, MN U.S.A. The duct mount and outside air mount sensors come standard with sintered filters to protect the sensor from particulates. The stylish housing is well vented to provide air flow across the sensor to improve measurement accuracy. Wall Mount Temperature Transmitter is a compact economical sensor for the building automation market space. It can be used for pressures up to 100 bar. Temperature measurement of liquid and gaseous media in Threaded mount temperature transmitters is used for Head mount temperature transmitter to convert TC/RTD/Linear volts/Linear resistance input signals into a scalable 4 to 20 mA analog output signal. Their compact designs, along with dual channel options, help accommodate multiple temperature measu Temperature Transmitters - DIN Rail MountĭIN rail mounted temperature transmitters offer high measurement accuracy, stability and reliability over a wide range of process and ambient temperatures. Temperature transmitter devices convert the input signal from a wide range of temperature sensors, such as resistance thermometers, thermocouples, and potentiometers, into a standardized analogue or digital output signal.
