1. Description

The Signet 2350 Temperature Sensor has a one-piece injection molded PVDF body that is ideal for use in high purity applications. It also outlasts metal sensors in aggressive liquids and eliminates the need for costly custom thermowells. These sensors are available with Digital (S3L) or ﬁ eld-scaleable 4 to 20 mA output. Dual threaded ends (3/4 in. NPT) allow submersion in process vessels, or in-line installation with conduit connection. Integral adapters (sold separately) may be used to create a compact assembly with ﬁ eld mount versions of the 8350 Temperature Transmitter.

The compact integral assembly can be installed using the following directions:

3.1 2350-1 Integral Assembly Sensor Modiﬁ cation

• Modify sensor part number 3-2350-1 per ﬁ gure 1.

• Apply sealant or PTFE tape to the process connection threads per ﬁ gure 2, after inspecting threads to ensure integrity. Do not install a sensor with damaged threads.

• Thread the sensor into the 3-8052 mounting kit.

• Tighten the sensor 1½ turns past ﬁ nger tight into the process connection.

• Make sure the ﬂ ow alignment indicator is in correct position in the pipe. Damage to the sensor tip can occur if the sensor tip is installed improperly.

• Install 8350 transmitter (refer to 8350 or 9900 manual for wiring information).

• The 3-8052 Integral kit includes:

• 3/4 in. NPT process connection

The optional 3-8052-1 Integral Junction box with ¾ in. process connection offers a convenient terminal point to extend the 2350 cable over distances greater than 4.6 m (15 ft).

• The kit includes:

• ¾ in. NPT process connection

• Conduit base and cap with junction terminals

• 3-9000.392-1 liquid tight connector, ½ in. NPT

To extend the wires longer than 4.6 m (15 ft):

• Modify sensor 3-2350-1 or 3-2350-3 as described in ﬁ gure 1.

• Terminate the three wires to the terminal board located in the cap assembly.

• Add customer-supplied wire to extend the cable.

• Terminate to the transmitter or the 4 to 20 mA input device.

• Apply sealant or PTFE tape to the process connection threads per ﬁ gure 3, after inspecting threads to ensure integrity. DO NOT install a sensor with damaged threads.

• Tighten the sensor 1½ turns past ﬁ nger tight into the process connection.

3.3 2350-1 or 2350-3 Submersible Installation

• Use the 2350-1 or 2350-3 sensor with 4.6 m (15 ft) cable.

• Mount the sensor to an extension pipe or watertight conduit using thread sealant.

• Use a cable gland at the top of the extension to prevent moisture intrusion/accumulation inside the pipe.

• For additional defense against possible accumulation of condensation at the back seal area of the sensor, ﬁ ll the lower 75 mm to 100 mm (3 in. to 4 in.) of conduit or extension pipe with a ﬂ exible sealant such as silicone.

4. Digital (S3L) Wiring

• All models of the 2350 provide Digital (S3L) output when powered with 5 VDC.

• Connecting the SHIELD to a direct Earth ground may reduce electrical noise interference.

• The maximum Digital (S3L) cable length is dependent upon the instrument to which the sensor is connected. Consult the instrument manual for details.

• Connect the 2350 cable directly to Digital (S

L) I/O terminals.

The 4 to 20 mA endpoint values are independent of one another and may be adjusted in the ﬁ eld. For example, to reduce the 20 mA endpoint value from the factory setting of 100 °C, but to allow the 4 mA endpoint to remain at 0 °C, perform only the steps listed in 6.2 below.

NOTE: The RED wire, which is not connected during normal

4 to 20 mA operation, assumes an important role in the following procedures.

6.1 To adjust the 4 mA endpoint in the ﬁ eld:

• Carefully remove the heat shrink tube protecting the red wire.

• Expose the sensor to the temperature desired to correspond with 4 mA

-10 °C to 100 °C (submersible: -10 °C to 85 °C). (Be sure to allow sufﬁ cient time for the sensor to reach equilibrium.)

• With power applied as described in Section 5, connect the RED wire to the WHITE wire for 15 seconds. (After about 10 seconds the output will drop to 3.6 mA and remain there until the RED wire is disconnected.)

• Disconnect the RED wire from the WHITE wire; the 4 mA endpoint has been adjusted.

• NOTE: The output will act as a switch if the 4 and 20 mA endpoints are set very near to the same value.

6.2 To adjust the 20 mA endpoint in the ﬁ eld:

• Expose the sensor to the temperature desired to correspond with 20 mA -10 °C to 100 °C (submersible: -10 °C to 85 °C). (Be sure to allow sufﬁ cient time for the sensor to reach equilibrium to this temperature.)

• With power applied as described in Section 5, connect the RED wire to the BLACK wire for 15 seconds. (After about 10 seconds the output will rise to 22 mA and remain there until the RED wire is disconnected.)

• Disconnect the RED wire from the BLACK wire; the 20 mA endpoint has been adjusted.

NOTE: The output will act as a switch if the 4 and 20 mA endpoints are set very near to the same value.

• Minimum span is ±2% of maximum range.

• After adjusting the 4 to 20 mA span, protect the red wire by installing the provided wire nut.

• For easier re-spanning use the Signet 0250 USB to Digital (S3L) Conﬁ guration/Diagnostic Tool.

Wire Nut

6.3 To restore the factory setting:

• Disconnect power to the sensor. Wait 10 seconds for circuit to discharge.

• Connect the RED wire to the WHITE wire.

• Apply power as described in Section 5, but with the RED wire connected to the WHITE wire for 15 seconds. (After about 10 seconds the output will drop to 3.6 mA and remain there until the RED wire is disconnected.)

• Disconnect the RED wire from the WHITE wire; factory settings have been restored.
