MGO - RTD

(Resistance Temperature Detectors) – a temperature sensing probe of finely wound platinum wire that displays a linear resistance change for a corresponding temperature change. The resistance increases as the temperature rises. A base resistance of 100 ohms at 32°F is the industry (DIN) standard.
General Purpose RTD
General Purpose RTD’s
Resistance Temperature Detectors (RTD’s) offer an unparalleled combination of quality, performance, and price to meet todays changing market. To meet a broad range of requirements the factory has designed RTD’s in three specific temperature ranges: the Low, Medium, and High range series. General specifications, features, and available configurations for each series are as follows:

LOW RANGE: -50 to +200°C (-58 to +392°F) The construction provides a cost effective and durable probe suitable for industrial process or laboratory applications and offers high accuracy, long term stability, superior interchangeability and resistance to shock and vibration. Element Types: Platinum 100W, 500W and 1000W ohms at 0°C (standard) (Nickel, Nickel-Iron and Copper available) Element Accuracy @ 0°C: + 0.5% to + 0.01% (Multiple DIN, DIN class A and B, Fractional DIN) Temperature Coef. (TCR): Alpha 0.00375W/°C (1000W), 0.00385W/°C (100W, 500W & 1000W), 0.00392W/°C (100W) Applicable Standards: DIN/IEC 60751 and JIS C1604 Other Specifications: Consult sales concerning information on stability, repeatability, self-heating and vibration Sheath Diameters: .050″ OD to 3/4″ OD (Metric sizes also available) Sheath Material: 316 stainless steel standard, other materials available Excitation Current: 1mA or less recommended, 2mA maximum (Consult sales for applications utilizing more than 2mA) Insulation Resistance: At 21°C (70°F) with all external surfaces dry, the resistance between any lead wire and the sheath is 500 megohms or greater at 250 VDC.

MEDIUM RANGE: -50 to +450°C (-58 to +842°F) This series utilizes the same basic construction as the low series, but offers the benefit of an extended temperature range. HIgh accuracy, long term stability, superior interchangeability and resistance to shock and vibration make this series a significant addition to our line of high quality RTD’s. Element Types: Platinum 100W, 500W and 1000W ohms at 0°C (standard) Element Accuracy @ 0°C: + 0.5% to + 0.01% (Multiple DIN, DIN class A and B, Fractional DIN) Temperature Coef. (TCR): Alpha 0.00375W/°C (1000W), 0.00385W/°C (100W, 500W & 1000W), 0.00392W/°C (100W) Applicable Standards: DIN/IEC 60751 and JIS C1604 Other Specifications: Consult sales concerning information on stability, repeatability, self-heating and vibration Sheath Diameters: 1/8″ OD to 3/4″ OD (Metric sizes also available)Sheath Material: 316 stainless steel standard, other materials available Excitation Current: 1mA or less recommended, 2mA maximum (Consult sales for applications utilizing more than 2mA) Insulation Resistance: At 21°C (70°F) with all external surfaces dry, the resistance between any lead wire and the sheath is 100 megohms or greater at 250 VDC.

HIGH RANGE: -200 to +650°C (-328 to +1202°F) This construction utilizes a fully supported, strain fee wire wound sensing element encapsulated in a compacted MgO insulated metal sheathed cable. This combination provides a probe suitable for extremely demanding applications. It offers superior resistance to pressure, shock, and vibration. By utilizing the finest elements available, this style of probe displays long life, longer term accuracy and excellent repeatability. Element Types: Platinum 100W at 0°C (standard) (Consult for other types) Element Accuracy @ 0°C: + 0.12% to + 0.01% (DIN class A and B, Fractional DIN) Temperature Coef. (TCR): Alpha 0.00385W/°C, 0.00392/W°C (100W) Applicable Standards: DIN/IEC 60751 and JIS C1604 Other Specifications: Consult sales concerning information on stability, repeatability, self-heating and vibration Sheath Diameters: 1/8″ OD to 1/2″ OD (Metric sizes also available) Sheath Material: 316 stainless steel standard, other materials available Excitation Current: 1mA or less recommended, 5mA maximum Insulation Resistance: At 21°C (70°F) with all external surfaces dry, the resistance between any leadwire and the sheath is 500 megohms or greater at 250 VDC.

MGO - Thermocouple

A thermocouple is a temperature sensing probe consisting of the junction of two dissimilar metals which has a millivolt output proportional to the difference in temperature between the “hot” junction and the lead wires (cold junction). 

All MgO cable meets or exceeds all applicable ANSI/ASTM standards.   MgO insulated thermocouples have many desirable characteristics (i.e. fast response, compact size, broad temperature range, formability, weld ability, durability, accuracy, thermal shock and vibration resistance).  These characteristics make the MgO an excellent choice for virtually all laboratory or process applications.  The standard MgO configuration consists of ANSI/ASTM standard limits of error conductor material and standard (96%) pure insulation.  Each catalog page details a variety of other configurations available.
