Honeywell STT250 Temperature Transmitter

Memory contains the characteristics of most commonly used temperature sensors.
Calibration of the LRV/URV end points will typically give accuracy improvements of 2 times.
Sensor errors can be calibrated out by calibration to the specific sensor either by having it at the LRV/URV temperatures or by simulation of the known values.

Physical Mounting, Construction and Integral Meters		The STT250 Temperature Transmitter is designed to be mounted in a DIN Form A housing for direct installation with the temperature sensor or can be provided in a remote pipe or wall mount housing. Details on the various housings and integral meters available are given in specification sheet EN0I- 6032. The STT250 Temperature Transmitter module can also be DIN rail mounted to a top hat or “G” rail via a clip.

Probe and Thermowell Availability		STT250 can be supplied complete with any of the previously listed thermocouple or RTD sensors and with any of a wide range of thermowells. The sensors are of Mineral Insulated (MI) construction with lengths of up to 2 meters available. For the direct head mount installation the sensor is supplied with a mounting plate for STT250 module attachment and fixing screws to provide the spring loaded attachment to the housing. For EEx d IIC T6 applications a flame trap is included between the sensor and sensor entry of the housing. See details on the standard sensors available in EN0I-6033 for Europe, or 34-44-29-01 for North America.

Additional Parameters		Output: 4-20mA or Honeywell digital DE protocol. HART and DE available with 4- 20mA output. Adjustment range: No limits to adjustments within the Maximum Range except minimum span limit of 1 engineering unit e.g. 1°C Damping time constant: Adjustable from 0 to 102 seconds digital damping. Output response time: 1 second to reach 63% of final value with 0 secs damping. Output update time 0.5 secs approximately. Input/ output galvanic isolation Withstands 500Vac dielectric strength test for 1 minute. Sensor open circuit Open circuit/ burnout detection is user selectable. Upscale or downscale with critical status message. Latching or nonlatching sensor burnout action. Common mode rejection 120dB (1 million to 1) from 50Hz to 50 kHz. Series mode rejection 40dB (100 to 1) for 50 or 60Hz ±0.5Hz. with internal software filter set to local power line frequency). EMC compliance In compliance with 89/336/EEC, ElectroMagnetic Compatibility (EMC) Directive. RFI rejection: ±0.1% of span at 30V/m over 20 to 1,000MHz in metallic housing and with shielded cables.
