LabomCB6010Compact Pressure Transmitter, 100 bar, 4–20 mA 2-Wire, Piezoresistive, Internal Diaphragm, Welded Stainless Wetted Parts, IP65, Non-Ex

Product Description

What this part is

This is a Labom COMPACT series pressure transmitter with a 100 bar range, a piezoresistive sensing element and a 4–20 mA two-wire output. It converts process pressure into a load-independent current signal for a PLC analog input, a panel indicator or a control loop. The wetted parts are stainless steel and fully welded, the case is stainless steel, and it is built for tough process service rather than clean laboratory duty.

Hazardous-area certification: this unit is the non-Ex version:
On a pressure transmitter this is often the entire buying criterion, and it is decided by a single digit in the order code.

The Labom order code for this series runs CB601x, where the final digit selects explosion protection: 0 = without Ex protection, 1 = II 2G Ex ib IIC T6 Gb intrinsically safe to ATEX under TUV 00 ATEX 1557 X. This unit is CB6010. The final digit is 0, so this is the standard, non-Ex transmitter.

The correct application for this version is general industrial service — hydraulics, machine tools, water and general process plant outside a classified area. The intrinsically safe unit for a Zone 1 or Zone 2 loop behind a barrier is the CB6011.

Decoding the order code

CB: Labom COMPACT pressure transmitter with an internal diaphragm. The parallel CE series (CE611x / CE612x) is the flush-mounted diaphragm version for dead-zone-free measurement on viscous or solids-bearing media. CB and CE are not interchangeable in a process connection.

601: internal diaphragm, media temperature up to 80 °C. The CB602x variant is the same body rated for media up to 140 °C.

0: explosion protection, without.

Range, process connection, output and options are specified by further order blocks. H1 designates the 4–20 mA two-wire output, and K-codes designate the process thread: K1002 = G1/4 B per EN 837-1, K1010 = G1/2 B, K1024 = G1/4 A.

Also written CB-6010, CB 6010 and, at series level, CB60.. / CB60xx.

Published specifications

Measuring range, this unit: 100 bar (series covers 0…1 bar to 0…400 bar).

Measuring principle: piezoresistive.

Diaphragm: internal.

Output signal: 4–20 mA, 2-wire technology.

Linearity error including hysteresis: within 0.2% of full scale.

Adjustment: approximately ±5% of full scale; zero point and measuring span separately adjustable.

Response delay: 20 ms or less.

Wetted parts: stainless steel, completely welded.

Case: stainless steel as standard (field housing also offered in the series).

Degree of protection: IP65 standard, IP67 optional.

Ambient temperature: −25 to 70 °C.

Media temperature: −10 to 80 °C (this CB601x variant).

Storage temperature: −40 to 90 °C.

Explosion protection: none on this order code.

EMC: noise immunity to EN 50082 part 2 (industrial); emitted interference to EN 50081 part 1. The device has no emission of its own.

Mounting data

Process connection: threaded, specified by K-code — K1002 = G1/4 B per EN 837-1, K1010 = G1/2 B, K1024 = G1/4 A. These threads are not interchangeable.

Media temperature limit: 80 °C on this CB601x variant; the separate temperature decoupler accessory extends the series to short-term 140 °C sterilisation duty.

Electrical: two-wire loop, polarity sensitive, with the loop supply required to deliver 20 mA at the terminal voltage.

Adjustment: zero point and measuring span are separately adjustable over approximately ±5% of full scale.

What these specs mean in practice

Two-wire 4–20 mA is the most forgiving analog interface there is: two conductors carry both power and signal, the current loop is immune to voltage drop over long cable runs, and a broken wire reads as 0 mA rather than as a plausible pressure. That is why this style of transmitter is still specified for new work.

Separately adjustable zero and span, at roughly ±5% of full scale, is more useful than it sounds on a surplus unit. It trims out a small offset from a different mounting height or a slightly different reference without recalibrating the loop in software, and it matches the transmitter to an existing indicator scaled for the original installation.

Linearity within 0.2% of full scale on a 100 bar range means about ±0.2 bar across the span — appropriate for pressure control, pump and compressor monitoring, hydraulic system supervision and general process work. It is a process instrument rather than a laboratory reference standard.

The completely welded stainless wetted section is what makes this transmitter suitable for chemical and petrochemical service, shipping and general process engineering. No elastomer seal in the pressure path means no compatibility question about the seal material and no seal to swell or extrude.

IP65 as standard is dust-tight and protected against water jets, which suits a plant interior or a covered installation. The series offers IP67 as an option for washdown or outdoor duty.

Quantity and configuration

Transmitter only, one unit. The mating process fitting, adaptor and gasket, the temperature decoupler accessory, the electrical connector or cable and gland, the loop power supply, a calibration certificate and any bracket or mounting hardware are each ordered separately. The photographs show the hardware fitted to this unit.

Interchange guidance

Search forms include CB6010, CB-6010, CB 6010, Labom CB60 and CB60xx. Within the family, these are related models rather than equivalents: CB6011 is the intrinsically safe Ex ib version of this transmitter and is the one required for a classified area; CB6020 / CB6021 are the 140 °C media variants; CE6110 / CE6111 and CE6120 / CE6121 are the flush-diaphragm versions. Range and process connection are separately coded, so two units both marked CB6010 can still differ in range and thread — match the range as well as the model. Labom GmbH is a German manufacturer and the CB60 / CE61 COMPACT series remains a current catalogue line, so a like-for-like new unit is available to match an existing loop exactly.
